The topic of this thesis is solar pump Neodymium doped Yttrium Aluminum Garnet laser, the research of characteristics is that natural sunlight is used as pumped source in instead of diode laser, pulsed Xenon lamp, Krypton arc lamp¡Ketc. In order to reduce use of electric power. By using solar concentrator system, concentration is reached to 8.89 ¡Ñ (10^10). This ratio is set to end pump Neodymium doped YAG. The output power is up to 17.54mW, and the laser slope efficiency is up to 0.04% . On application, If lasers are needed in remote locations where sunlight is abundant and other forms of energy are scarce, a solar laser would seem to be a natural choice.
