摘要

在 20 至 70°C 的工作温度范围内，在放电电容标称值为 22 nF 和控制电流振幅为 10.4 mA 的条件下，对带宽为 200 μm、长度为 980 μm 的半导体激光晶闸管的输出光功率、激光振荡光谱、光脉冲持续时间和接通延迟进行了测量。结果表明，激光晶闸管具有很高的温度稳定性。当器件从 20°C 加热到 70°C 时，峰值输出功率的降低程度在电源电压为 4-20 V 时不超过 15%，在电压为 3 V 时不超过 25%；振荡光谱中心波长的移动平均为 0.21 nm/°C。

Temperature Dependence of the Output Optical Power of Semiconductor Lasers–Thyristors Based on AlGaAs/GaAs/InGaAs Heterostructures

Measurements of the output optical power, laser-oscillation spectra, optical-pulse duration, and switching-on delays of semiconductor lasers–thyristors with a strip width of 200 μm and a length of 980 μm were performed in the operating temperature range from 20 to 70°C at a nominal value of the discharge capacitor of 22 nF and a control-current amplitude of 10.4 mA. It is shown that lasers–thyristors have high temperature stability. When the devices were heated from 20 to 70°C, the level of reduction of the peak output power did not exceed 15% for supply voltages of 4–20 V and 25% for a voltage of 3 V; the shift of the central wavelength of the oscillation spectrum was on average 0.21 nm/°C.
