The experimental constituents of the GOST are the evanescent-wave diode laser, a titanium:sapphire laser to create the hollow beam and an additional diode laser to provide the light for the repumping beam. For EW and repumping beam we use laser diodes (SDL-5712-H1, distributed Bragg reflector), whic ...
