Double clad planar waveguide Nd:YAG laser

Popis výsledku v původním jazyce

Operation of a diode-end-pumped double-clad planar waveguide Nd:YAG laser is reported. The waveguide structure consisted of 220 um thick active Nd:YAG layer sandwiched between two 390 um undoped YAG layers. The outer cladding was formed by two 200 um sapphire layers. Dimensions of the whole structure are 12 x 6 x 1.4 mm3. With pumping by 2 W laser 808 nm diode, the laser operation was achieved at 1.06 um with several resonator configurations: plan parallel resonator with external mirrors, self-imaging resonator, and resonator with mirrors coated on waveguide structure faces. In multimode operation the slope efficiency was 58%. The aximal output power of 640 mW was achieved. In single mode operation with self-imaging resonator the slope efficiency of 34% was achieved. With mirrors coated directly on waveguide structure faces the slope efficiency of 49% in single transversal mode was obtained.
