We demonstrate what we believe to be the first demonstration of stable gain-switched 845-nm pulse generation by a weak modulated 1550-nm seed laser from an Er3+-doped fluoride fiber pumped by a CW 974 nm LD.
A record 2,4 MW peak power, actively Q-switched Er:YAG laser is presented. For 10 Hz repetition rate 21 mJ, 86 ns pulses at the wavelength of 2940 nm were achieved. The beam divergence was 2,3 mrad.
We present an efficient in-band-pumped Er(0.2 at.%):Sc2O3-laser at 1581 nm with a maximum output power of 0.95 W and a maximum slope efficiency of 31%.
We report an Er:YAG ring laser employing an acousto-optic modulator to enforce unidirectional operation. The laser yields 4.7 W of single-frequency output at 1645 nm in a beam with M2~1.03 for 14 W of pump power at 1532 nm.
Laser performance of Er3+-doped Y2O3 ceramic is reported for the first time. Resonantly-pumped, eyesafe, 1.6-mum Er:Y2O3 cryo-laser slope efficiency of ~48% and output power ~7 W have been achieved in this first experiment.
We present spectroscopic results on Er:YAG at 300 K-550 K with respect to resonant pump absorption at 1.53 mum and laser emission at 1.61 mum and 1.64 mum and numerical results on laser performance.
