Experimental study on diode pumping inorganic liquid laser output

In order to explore new high power laser systems, a liquid laser pumped by diode was build up. In the experiment, diode laser was adopted to pump neodymium ion doped inorganic laser liquid on single side. By measuring the near field profile, pulse shapes and the spectrums of the output light, liquid laser output was proved. Laser wavelength is 1 053 nm. A laser pulse output energy value reached 47 mJ and optical to optical efficiency 14%. Its optical efficiency was much higher than that of flash lamp as pump light source, which shows that liquid lasers has the outlook to high power laser systems.
