ACENTRIC DISORDERED ND3- A BROAD-BAND LUMINESCENCE MATERIAL WITH HIGHTHERMAL-CONDUCTIVITY TO GENERATE PICOSECOND LASER-PULSES(LA3GA5SIO14 CRYSTAL )

The disordered acentric Nd3+:La3Ga5SiO14 crystal with trigonal Ca3Ga2G e4O14 structure is tested in an actively and passively mode-locked las er system, which generates stable single pulses of 5.8 ps duration at pulse energy 250 mu J and wavelength lambda = 1067 nm (F-4(3/2)-->I-4( 11/2) laser channel). The pulse repetition rate can be increased to ab ove 10 Hz. The disordered laser crystal delivers comparable output ene rgy with higher stability compared with phosphate laser Nd3+:glass. So me important physical properties of La3Ga5SiO14 are considered.
