Abstract
This paper presents a compact diode-pumped continuous-wave Er:YLF laser emitting radiation at 2.8 µm with output power 2.9 W and slope efficiency 26.2%. Moreover, the <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"> <mml:mi>Q</mml:mi> </mml:math> -switching regime was successfully tested with a Fe:ZnSe polycrystal used as a modulator. Passive <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"> <mml:mi>Q</mml:mi> </mml:math> -switching results in the shortest pulse duration of 21 ns with repetition rate 50 kHz and peak power 252 W.
