1.55 μm Narrow-Linewidth Pulsed Laser Based on MgO:PPLN

open access: yesPhotonics, 2023
A high-power narrow-linewidth 1.55 μm pulsed laser, based on MgO:PPLN OPO, has been achieved using a F–P etalon. The pump source is a 1064 nm acousto-optical (AO) Q-switched Nd:YAG laser with a repetition rate of 10 kHz.
