Deliver Highest Available Efficiency
SANTA CLARA, Calif., Jan. 25 -- Coherent Inc. said its newest fiber array package (FAP) diode lasers deliver the highest efficiency in the industry. Now available at 940 nm and 980 nm, these FAPs produce 40 W of CW power through an 800-µm fiber bundle, with a numerical aperture of <0.11. These lasers are conduction cooled and produce a wall-plug efficiency (WPE) of >50%, which is significantly higher than the 35% efficiency of earlier generation FAPs.

Coherent said they are the first in a series of high-brightness products being developed that use high-efficiency epitaxy bars. High efficiency offers the customer several important benefits, the company said: It lowers the power supply requirements of the FAP itself, resulting in reduced system cost, size and weight; it reduces the amount of dissipated heat, minimizing the number or power of thermoelectric coolers required in the system, reducing the overall system power requirements and cost; and it increases the lifetime, due to decreased junction temperature rise, of the device.

The new 940-nm and 980-nm FAP products are primarily targeted at medical applications and fiber laser pumping. Medical uses include therapeutic applications in dermatology and surgery, where they enable new developments in laser-enabled cardiac surgery. As pump lasers, the new lasers are also ideal for both erbium- and ytterbium-doped fiber lasers, Coherent said.
