3S Displays Stable 1064nm Laser at High Power

NOZAY, France, Feb. 8, 2010 – French manufacturer of optical and optoelectronic components for telecommunication networks, 3S Photonics, demonstrated reliable pulsed-operation of its 1064nm wavelength-stabilized diode lasers at high power during a technical presentation at the SPIE Photonics West exhibition held in San Francisco.

Most pulsed fiber lasers are built on a Master Oscillator – Power Amplifier (MOPA) architecture. This configuration has the advantage, among others, of exploiting direct modulation of the diode laser seed (the MO) to reach high repetition rates and high peak-power pulsed operation. To enhance the fiber lasers global performance and reliability, high power single-lateral-mode 1064nm diodes with outstanding long-term behavior are needed. The reliability of these devices at high power has been a challenge for years, due to the high built-in strain in the Quantum Well (QW).

“The 1064nm single-lateral-mode laser diodes developed by 3S Photonics have demonstrated state-of-the-art reliability results, in both continuous wave and pulsed conditions exceeding 1W peak-power at 2.35A,” explained Yannick Bailly, vice president of Marketing and Product Lines Management at 3S Photonics. “Aging tests in continuous wave conditions prove the intrinsic robustness of our 1064 CHP seed laser modules even at very high junction temperatures, while specific tests in pulsed-operation at 45 °C and high repetition rates of several hundred kHz, confirm the stability of the devices in accelerated conditions representative of operating applications.”

Both free-running and wavelength stabilized - by means of a Fiber Bragg Grating (FBG) - packaged devices show very stable performances under pulsed conditions.
