Abstract
Diode-pumped crystals provided recently new compact laser devices. We report the first end pumping of a Lax Nd1-xMgAl11O19(LNA) crystal using a 200mW diode array (Spectra Diode Lab). We also report the first results obtained with a 1mW diode (SONY). This C.W. laser can be tuned from 1.048µm to 1.086µm. Without selective elements in the cavity, the laser emits around 1.054µm with a threshold of 24mW and a slope efficiency of 4.4% (output mirror of transmission T = 1%) when pumped by the diode array. With the selective elements, the threshold increases to 100mW and we obtain a power of 4mW for a pump power of 200mW.
