Development of high average and peak power laser around 2 μm based on cryogenically cooled Tm:Y2O3 transparent ceramic

2020
We demonstrated a cryogenically cooled Tm:Y2O3 master oscillator emitting around 1932.5 nm, which was tuned from 10 to 1000 Hz. Maximum pulse energy of 1.8 mJ (10 Hz) was achieved with 32 ns pulse duration.
