Santa Clara, Calif. A series of conductively-cooled diode laser bars from Coherent, Inc. offers high power and extended lifetime even under adverse operating conditions such as elevated operating temperatures, frequent power cycling and extreme shock and vibration.
The PulseLife Conductively Cooled Package (CCP) series of single laser bars use telecom-grade solder technology to bond the laser die directly to its heat sink, and the company's Aluminum-free Active Area (AAA) epitaxy at 810 nm, and high-efficiency 940-nm and 980-nm material systems. MTTF is rated at over 10,000 hours at an output power of 50 watts.
The PulseLife CCP lasers are suitable for demanding tasks in materials processing and medical applications. In addition, they offer 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 extreme shock and vibration. The devices also offer ease of integration, featuring an optical fill factor of 30%, which facilitates fiber coupling and lensing of the output.
