Laser Diodes Feature Improved Performance and Durability

Operating efficiency has been increased by 15%

Material and design enhancements promise to boost the performance of a new generation of single quantum well (SQW) laser diodes. Improved electro-optical and thermal-mechanical properties are among the products' features, according to Osram Opto Semiconductors Inc. (San Jose, CA). The diodes are robust and resist thermal fatigue, even during challenging pulse sequences. Other improvements include a lower laser threshold and 
a 15% increase in operating efficiency.

A reliable high-power diode laser bar is suited for a variety of medical applications. The SPL LG81 laser bar is sealed in an OEM package withfast-axis collimation. It is designed for continuous-wave and pulsed operation. A stable mounting technology fosters production efficiencies and reproducibility. The unit has a partly external micro-channel cooler that yields output power of up to 30 W and withstands 10o-30oC temperatures. The SMT-compatible laser bar can be operated with activeor passive cooling.

The company also offers a red laser diode, produced for the first time in an indium-gallium-aluminum-phosphide material. It features an optical output of 0.5 W and a wavelength of 650 nm. The SPL CG65 red laser diode is Osram's first foray into the visible high-power laser diode market. It is suitable for a number of medical applications including photodynamic therapy for cancer treatments, ophthalmology, and dermatology.
