Conductively cooled diode laser bars are
reliable
A new series of conductively cooled semiconductor laser bars from Coherent (Santa Clara, CA) promises both high power and extended lifetime, even under adverse operating conditions
The PulseLife conductively cooled package (CCP) series of single laser bars utilises telecom-grade solder technology to bond the laser die directly to its heatsink This approach is complemented by the proven performance of Coherent's aluminium-free active area (AAA) epitaxy at 810nm, as well as its high efficiency 940nm and 980nm material systems

Violet laser producing power from 4mW to 30mW at 408nm for series a range of applications including cytometry, high-throughput screening, and confocal microscopy
Together, these deliver over 10,000 hours of lifetime (MTTF) at output powers of 50Watts.
Most importantly, 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 says the company.
In addition, they offer the performance characteristics necessary for military applications in which the laser is subjected to elevated operating temperatures (as high as 75C), frequent power cycling and extremes of shock and vibration.
PulseLife CCP lasers have also been designed with ease of integration in mind; for example, they feature an optical fill factor of 30%, which facilitates fiber coupling and lensing of the output.
