Tunable Diode-Pumped-Lna Laser

Abstract

Diode-pumped crystals provided recently new compact laser devices. We report the first end pumping of a La Ndl-xMgAEl,Ol,(LNA) crystal using a 200mW diode array (Spectra Diode Lab). We also rgport the first results obtained with a ImW diode (SONY). This C.W. laser can be tuned from 1. 0 4 8~ to 1.086pm. Without selective elements in the cavity, the laser emits around 1.054pm with a threshold of 24mW and a slope efficiency of 4.4% (outputmirrorof transmission T = 1%) when pumped by the diode array. With the selective elements, the threshold increases to lOOmW and we obtain a power of 4mW for a pump power of 200mW.
