Dewar design for optically pumped semiconductor lasers

A liquid‐nitrogen Dewar has been constructed to allow precise and stable alignment of semiconductor platelets. Laser action in an external cavity is observed when the platelets are longitudinally pumped by an Ar+ laser. A microscope objective mounted inside the Dewar is used to focus both the pump a...

Zusammenfassung:A liquid‐nitrogen Dewar has been constructed to allow precise and stable alignment of semiconductor platelets. Laser action in an external cavity is observed when the platelets are longitudinally pumped by an Ar+ laser. A microscope objective mounted inside the Dewar is used to focus both the pump and the semiconductor laser beam to a 5‐μm spot. The sample can be moved and tilted while being kept at a temperature of 85 K. Sample mounting techniques are also described.
