Successfully used in space: a micro-integrated diode laser module

This example shows a hybrid micro-integrated narrowband laser module consisting of an extended cavity diode laser and a semiconductor-based optical amplifier (semiconductor optical amplifier). The module provides more than 500 mW of optical power at 1064 nm output with a linewidth of about 20 kHz. It was tested successfully in spring 2018 on board of a sounding rocket, where it served as a local oscillator of a highly stable iodine-based optical frequency reference.

The ceramic has a base area of ​​80 x 30 mm2.
