Bought this about a year ago, it has been a great laser. Not sure what diode or current Andy used with it, but it seems very stable. The Andy225 is in great condition with only a small scratch or so. Will incude a pair of e2 lituium batteries and a nice Andy custom sticker with the laser. ;D I will also include a 7mW 635nm pointer built by me free in this sale. (its kinda beat up, but still works like new) :D Looking for around $110 shipped for this set. Will consider offers and trades. ;)

Laser diode principles
Basic principles of laser diode technology

A number of questions and misconceptions surround the laser diode. Are all laser diode specifications identical? Do single-mode diodes always operate as single-mode? What effect does temperature change have on wavelength and optical power? The following explores these and other common diode questions and principles.

Are all laser diodes with the same model number identical?

Individual diode specifications generally vary from one diode manufacturing lot to another. These variances, typically minor and insignificant, may appear as changes in wavelength or in divergence angles or ratios. During diode manufacturing, variations in materials and layer thickness often account for differences in center wavelength and operating current. To denote potential changes from one diode to another, laser
diode manufacturers—like most other manufacturers—allow for tolerances in their specifications. For example, diode manufacturers typically report most visible diode specifications at a center wavelength ±10nm. If a specific wavelength is required, we at Power Technology, Inc. offer wavelength selection at a minimal cost.

What effect does temperature change have on wavelength & optical power?

Maintaining an optimum operating temperature for a laser diode can be extremely important. Changes in temperature translate into changes in wavelength and optical power. Unlike gas laser wavelengths—which are determined by atomic transitions—laser diode wavelengths are inherently unstable. The wavelength of a typical Fabry-Perot laser diode typically changes 0.3nm per degree Centigrade. Therefore, for every 3
degrees’ change, the wavelength of the laser diode can change nearly 1nm. If operated in constant current mode, diode output power tends to decrease as temperature increases, and diode power can exceed its maximum rating with a decrease in temperature. For this reason, we recommend choosing the automatic power control mode of operation, or using a laser module with active temperature control for constant
current mode of operation.

What spectral changes can occur from diode to diode?

One misconception about single-mode diodes is that they are always single-mode. Most single-mode laser diodes operate as such only when driven at or near their recommended operating current. When operated at a lower-than-recommended operating power, a single-mode laser diode can function as if it were multi-mode. For this reason, if single mode output is desired, users should employ a neutral density
filter to decrease the intensity of the beam without changing the spectral distribution of the energy.

Does raw diode power equal module output power?

When purchasing a laser diode module, keep in mind that the output power of the module will be less than the maximum rated power of the laser diode. This result can be attributed to several factors: optical loss, CDRH safety margins, and general derating of laser modules due to PTI’s knowledge and experience regarding certain diodes. Always ask your sales engineer what output power your laser module will have with a particular laser diode installed.

LG, SHARP, CHUNGHWA AGREE TO PLEAD GUILTY, PAY TOTAL OF $585 MILLION IN FINES FOR PARTICIPATING IN LCD PRICE-FIXING CONSPIRACIES
LG to Pay $400 Million Fine, Second Highest Antitrust Division Criminal Fine Ever Imposed

WASHINGTON - Three leading electronics manufacturers-LG Display Co. Ltd., Sharp Corp. and Chunghwa Picture Tubes Ltd.-have agreed to plead guilty and pay a total of $585 million in criminal fines for their roles in conspiracies to fix prices in the sale of liquid crystal display (LCD) panels, the Department of Justice announced. Of the $585 million in fines, LG will pay $400 million, the second highest criminal fine ever imposed by the Department's Antitrust Division.
Today's charges were filed in U.S. District Court in San Francisco. The companies have agreed to cooperate with the Department's ongoing antitrust investigation.
Thin-Film Transistor-Liquid Crystal Display (TFT-LCD) panels are used in computer monitors and notebooks, televisions, mobile phones, and other electronic devices. In 2006, the worldwide market for TFT-LCD panels was approximately $70 billion. Companies directly affected by the LCD price-fixing conspiracies are some of the largest computer, television and cellular telephone manufacturers in the world, including Apple, Dell and Motorola.

"Today's charges and criminal fines emphasize the commitment of the Department of Justice to crack down on international cartels," said Attorney General Michael B. Mukasey.
LG Display Co. Ltd, a South Korean corporation, and its wholly-owned subsidiary, LG Display America Inc., a California company (LG), agreed to plead guilty to participating in a conspiracy from September 2001 to June 2006 to fix the price of TFT-LCD panels sold worldwide. During the conspiracy, LG Display Co. Ltd. was known as LG.Philips LCD Co. Ltd. (a joint venture between LG Electronics and Philips Electronics) and LG Display America Inc. was known as LG.Philips LCD America Inc.
Sharp Corp., a Japanese consumer electronics manufacturer, has agreed to pay a $120 million fine for its participation in separate conspiracies to fix the price of TFT-LCD panels sold to Dell Inc. from April 2001 to December 2006 for use in computer monitors and laptops; to Motorola Inc. from fall 2005 to the middle of 2006 for use in Razr mobile phones; and to Apple Computer Inc. from September 2005 to December 2006 for use in iPod portable music players.
Chunghwa, a Taiwanese TFT-LCD panel manufacturer, has agreed to pay a $65 million fine for its participation with LG and other unnamed co-conspirators in a conspiracy from September 2001 to December 2006 to fix the price of TFT-LCD panels sold worldwide.
"These price-fixing conspiracies affected millions of American consumers who use computers, cell phones and numerous other household electronics every day," said Thomas O. Barnett, Assistant Attorney General in charge of the Department's Antitrust Division. "These convictions, and the significant fines they carry, should send a clear message that the Antitrust Division will vigorously investigate and prosecute illegal cartels, regardless of where they are located."
LG and Chunghwa are charged with carrying out the conspiracy by:
  • Participating in meetings, conversations, and communications in Taiwan, Korea and the United States to discuss the prices of TFT-LCD panels;
  • Agreeing during those meetings, conversations and communications to charge prices of TFT-LCD panels at certain pre-determined levels;
  • Issuing price quotations in accordance with the agreements reached; and
  • Exchanging information on sales of TFT-LCD panels, for the purpose of monitoring and enforcing adherence to the agreed-upon prices.
Sharp is charged with participating in three separate conspiracies, to fix the price of TFT-LCD panels sold to Dell, Motorola and Apple by:
  • Participating in bilateral meetings, conversations, and communications in Japan and the United States to discuss the prices of TFT-LCD panels to be sold to Dell, Apple and Motorola;
  • Agreeing during those bilateral meetings, conversations and communications to charge prices of TFT-LCD panels at certain pre-determined levels to Dell, Apple and Motorola;
  • Issuing price quotations in accordance with the agreements reached; and
  • Exchanging information on sales of TFT-LCD panels to be sold to Dell, Apple and Motorola, for the purpose of monitoring and enforcing adherence to the agreed-upon prices.
LG, Sharp and Chunghwa are each charged with price fixing in violation of the Sherman Act. Each violation carries a maximum fine of $100 million for corporations. The maximum fine may be increased to twice the gain derived from the crime or twice the loss suffered by the victims of the crime, if either of those amounts is greater than the statutory maximum fine.
LG Display Co. Ltd., based in Seoul, South Korea, reported $15.3 billion in revenue for 2007.
Sharp, based in Osaka, Japan, reported $34.2 billion in revenues for its fiscal year ending March 31, 2008, including $6.8 billion in revenue from LCD sales.
Chunghwa, based in Taoyuan, Taiwan, Republic of China, reported $4.8 billion in revenue for 2007.
These pleas are the result of a joint investigation by the Antitrust Division's San Francisco Field Office and the Federal Bureau of Investigation in San Francisco. The plea agreements are subject to court approval.
Anyone with information concerning illegal conduct in the TFT-LCD industry is urged to call the San Francisco Field Office of the Antitrust Division at 415-436-6660.
