PulseLife CCP Lasers
Feb 2007
Coherent Inc.Request Info
SANTA CLARA, Calif., Feb. 26, 2007 -- A new series of conductively cooled semiconductor laser bars from laser-based solutions provider Coherent Inc. offers both high power and extended lifetime, even under adverse operating conditions, the company said.

CoherentLaserDiodeBar.jpgThe PulseLife Conductively Cooled Package (CCP) series of single laser bars utilizes telecom-grade solder technology to bond the laser die directly to its heatsink. This approach is complemented by the performance of the company's aluminum-free active area (AAA) epitaxy at 810 nm, as well as its high efficiency 940-nm and 980-nm material systems. Together, these deliver over 10,000 hours of lifetime (MTTF) at output powers of 50 W. Most importantly, Coherent said, the optimum balance between thermal conductivity and expansion coefficient matched packaging maintains this reliability under torturous "on-off" cycle conditions.

This high durability, together with the convenience of conductive cooling, make PulseLife CCP lasers ideal for demanding tasks in materials processing and medical applications, the company said. In addition, they offer the performance characteristics necessary for military applications in which the laser is subjected to elevated operating temperatures (as high as 75 °C), frequent power cycling and extremes of shock and vibration.

Coherent said PulseLife CCP lasers have also been designed with ease of integration in mind; for example, they feature an optical fill factor of 30 percent, which facilitates fiber coupling and lensing of the output.
