PulseLife Horizontal Arrays
Apr 2007
Coherent Inc.Request Info
SANTA CLARA, Calif., April 26, 2007 -- PulseLife horizontal arrays from Coherent Inc. are a new series of diode laser packages that deliver high-power output while offering simplified water-cooling requirements.

Utilizing Coherent's new PulseLife telecom-grade solder technology and its proven AAATM (aluminum-free active area) epitaxy, these products are available in two-bar or three-bar linear arrays, with output powers of 80 W and 120 W, respectively, at 808 nm.

CoherentPulseLife.jpgThe use of Coherent's all-new macrochannel cooling architecture in these devices eliminates the corrosion problems that have plagued other diode laser cooling approaches; this new design enables the use of plain, filtered (<100 µm) industrial cooling water, without the cost and complexity of a water-conditioned control system, the company said.

PulseLife horizontal arrays are primarily intended for solid-state laser pumping applications. The PulseLife's compact size facilitates placement around the laser crystal within the resonator. Integration is further simplified because the laser bar heat-sink is electrically isolated. PulseLife arrays also feature superior lifetime characteristics, with a mean time to failure (MTTF) of over 20,000 hours, further lowering their total cost of ownership, Coherent said.
