Abstract :
Demonstrations of CW and pulsed microchip lasing in Cr2+:ZnS and Cr2+:ZnSe crystals are reported. Slope efficiencies up to 53% with output power up to 150 mW for CW and energy up to 1 mJ for pulsed pumping were achieved. Two compact diode and Er fibre laser directly pumped external cavity Cr2+:ZnS lasers are also described.
