High Brightness 793nm, Single-Emitter Based Fiber-Coupled Pump Module

Mainz, Germany

DILAS, the diode laser company, introduces a new high brightness single-emitter based, fiber-coupled diode laser pump module that delivers 9W output power into a 106.5μm fiber core at a wavelength of 793nm, with a numerical aperture of 0.15.

The small footprint and low height design is offered in a simplified and robust package measuring 61.9 x 21.5 x 9.6 mm³. The output power is attained by optically combining into the delivery fiber the output of electrically series connected single emitters. At 9W output power, the device features a maximum operating current of 4.0A with >40% efficiency. Also, high-temperature operation at 45 degrees Celsius is attainable, allowing for less dedicated cooling capacity or operation in a harsh environment.

The single-emitter, fiber-coupled diode laser pump module is suitable for pumping thulium-doped (Tm3+) fiber lasers for eye-safe applications.
