High-efficiency cavity doubling laser
 A high-efficiency cavity doubling laser according to the invention contains a laser diode, a laser crystal and a non-linear crystal, is characterized in having a first gap between the laser diode and the laser crystal and a second gap between the laser crystal and the non-linear crystal. Therefore, heat created by the laser crystal can be dissipated by the air gaps and cannot be directly conducted to the laser diode and the non-linear crystal. Furthermore, the thermal distortion of the laser crystal can be compensated by adjusting the position of the non-linear crystal, thereby increasing the efficiency of the laser.
