MultiJunction Diode Lasers

Photonics Spectra
Dec 2020Multi-junction lasers from SemiNex Corp. are semiconductor diode devices at eye-safe wavelengths between 1310 and 1550 nm.

The multi-junction laser diode is a drop-in replacement for most compact laser drivers used for existing 9XX-nm diode systems. It makes use of three monolithic solid-state laser junctions that produce 80 W at 1550 nm with a 95-μm aperture width. The device enables eye-safe, autonomous lidar systems to reach >250 m without compromise and can be operated at pulse widths between 2 and 100 ns at 200- to 400-kHz pulse repetition rates.

Various aperture widths and cavity lengths are available to meet specific customer requirements. It is available in double and triple junction configurations in various packaging and submount configurations.More products
