Erbium active elements with a slit stop

Abstract

This paper proposes a method for improving the quality of the pulse generated by an erbium laser by means of a slit stop formed in the active element. It presents results obtained for a radiator with diode pumping, operating in a wide range of pulse-repetition rates from single pulses to 10 Hz. EXPERIMENTAn analysis of the pump-energy distribution inside the AE showed that, both in the case of lamp pumping and in the case of laser-diode pumping, the pumped zone has the 182
