The well defined spectral response of the DFB laser diodes - especially under pulsed operation - creating the smallest beam parameter product.
As a consequence the DFB-1064 has been qualified as a seed source for a fiber laser application to be used at NASAs C.A.T.S. program currently in service at ISS. Generally our complete 14-pin butterfly manufacturing line and supply chain is suitable for space applications.
Also space qualified DFB seed laser diodes at 1064nm and 1645nm to help measuring methane gas concentration for a better understanding of climate change.
