摘要：
The paper describes results obtained with a new type of GaSb based semiconductor distributed feedback multiple quantum well lasers operating in continuous wave mode well above room temperature. The lasers show good tunability both by current and temperature from 0 to +60 degrees C and current from threshold up to 120 mA. They all operate in high power (1-3 mW) single mode regime and can be tuned in the methane and ammonia overtone absorption spectral range over up to 12 cm(-1) and can be used for the detection of these and other gasses.
