摘要
为了实现远程气体探测,基于由超晶格材料构成的光参量振荡器,研制了一台双波长输出的中红外激光器。该光参量振荡器通过种子注入的方式,实现了纳秒级窄线宽的中红外脉冲激光输出,重复频率为500 Hz,单脉冲能量超过1 mJ,并能够对准2.6~4.0μm波长范围内的NO、NO_(2)和SO_(2)的吸收峰。通过气体动态排放实验,在远程气体探测实验中对该激光器进行了验证。
In order to achieve the purpose of long-range gas detection,a mid-infrared laser with dual wavelength output is developed;this system is based on an optical parametric oscillator composed of superlattice materials.The optical parametric oscillator realizes a mid-infrared pulsed laser output of nanosecond order with a 500 Hz repetition rate and a single pulse energy that exceeds 1 mJ through seed injection,and effectively aligns the NO,NO2,and SO2 absorption peaks in the 2.6-4.0μm range.The laser performance is validated in a remote gas detection experiment based on a gas dynamic emission experiment.
