Abstract

We demonstrate a high-power, wavelength tunable mid-infrared laser with a high-precision power attenuator. The output power is 5.1W at 3.8μm, achieved by an optical parametric oscillator (OPO) based on multichannel periodically-poled lithium niobate (PPLN). The repetition frequency is 10kHz, and the pulse width is 69ns. The wavelength is tunable from 3.708μm to 4.142μm. High-precision control on the power attenuator is obtained, the accuracy of the attenuator is 0.2dB from 0~27dB.
