Abstract

We report generation of broadly tunable (2.5-4 µm), narrow-band (0.04-0.35 cm-1) pulsed infrared radiation through a nanosecond optical parametric amplifier based on potassium titanyl phosphate (KTP) pumped by the second harmonic of a 10-Hz Nd:YAG laser. Input radiation at signal wavelengths of 615-662 nm was derived from a pulsed tunable dye laser system. Advantages of this device are simplicity, the broad range of infrared wavelengths to which a single dye in the dye laser provides access, and conversion efficiencies >10% at modest levels (<150 µJ) of input radiation.

摘要

我们报道了一种基于磷酸钛氧钾（KTP）的纳秒级光学参量放大器产生的宽可调谐（2.5 - 4 µm）、窄带（0.04 - 0.35 cm⁻¹）脉冲红外辐射，该放大器由10 Hz Nd:YAG激光器的二次谐波泵浦。信号波长为615 - 662 nm的输入辐射来自脉冲可调谐染料激光系统。该装置的优点包括结构简单、染料激光器中的单一染料能提供宽范围的红外波长、以及在适度的输入辐射水平（<150 µJ）下转换效率>10%。
