Study on the properties of LD-pumped Nd:LuVO 4 microchip laser

A new LD end pumped Nd：LuVO 4 microchip laser was reported for the first time. Study of laser properties was carried out on the effects of different Nd 3+ doped concentration，different cavity length and different 1064nm transmission. The relationship between the maximum output power and LD performance temperature was measured at different pump power. 923mW of continuous output at 1064nm with TEM 00 mode was obtained at 2W pump power，the pump threshold being 48mW. The slope efficiency was 52%，and increased to 59% when the microchip was cooled.
