Abstract

In this paper, we describe the temporal laser pulse dynamics of the 1.645 micrometers Er:YAG laser pumped by a 1.532 micrometers Er:glass laser. It can be shown that controllable double pulsing of the 1.645 micrometers laser action can be obtained by gain-switched type operation and a variable cavity loss. The rate equation dynamics model can predict this behavior, and thereby provide a design platform for generating controllable double pulsing outputs at high repetition rates. Applications to lidar techniques are discussed. Some innovative applications include polarization discrimination techniques in target detection technology and mitigating atmospheric turbulence effects in measurements.
