摘要: 1. 55μm半导体激光器有很多突出的优点,但普通的双异质结激光器功率小,且对温度很敏感。本文将大光腔结构形式引入1. 55μm GaInAsP/ InP半导体激光器中,用液相外延技术研制成功了脉冲峰值功率超过2W的1.55μm GaInAsP/InP半导体激光器。普通双异质结构激光器特征温度To为50~70K[1] ;而本文研制的大光腔结构为100~140K。激光器的寿命超过1 000h。

Abstract: The I. 55μm semiconductor laser has many distinctive special advantages, but the output power of ordinary double hetero-structure device is generally low and is dependent on temperature sensitively. Large optical cavity(LOC)is applied for the first time in a 1.55μm GaInAsP/ InP semiconductor laser, and the device obtained by liquid phase epitaxy techniques. The output power is over 2W, with a characteristics temperature (To) of the device 100?140K, while that of ordinary double hetero-structure laser devices can only attain 50?70K.Tlie lifetime of this LOC device is over 1000 hours.
