Abstract :
The laser beam of 0.5 at % Nd:doped concentration in Nd:YVO4 crystal bar is performed under low pumping power of laser diode. In this investigation, a micro-laser is formed by keeping a thickness of bar crystal to be as a plane-plane optical resonator. Diode laser (808 nm) was used as the pumping source. The pump power was focused to localize the high power density of source the crystal bar surface. As a result, excitation of Nd3+ atom produce stimulated emission with 1064 nm. Our experimental result shows the optical-optical conversion of the 0.5 at % Nd:doped concentration in Nd:YVO4 crystal bar is 4.8 % with threshold power of 1403.8 mW.
