    • A nonlinear optical crystal device, a wavelength conversion element, is surrounded with a heat sink having cooling fins. Cartridge heaters for uniformly heating the nonlinear optical crystal device are arranged in the heat sink, and the temperature of the cartridge heater is regulated by a heater controller. Laser light is input into the nonlinear optical crystal device, and delivered therefrom after its wavelength is converted into a shortened wavelength. When the repetition frequency of laser light is high, heating by the heaters is stopped, and cooling is effected with the heat sink. When the repetition frequency of laser light is low, heating by the heaters is carried out to maintain the temperature of the nonlinear optical crystal device to be a temperature at which a conversion efficiency is satisfactory.
    • 非线性光学晶体装置波长转换元件被具有散热片的散热片包围。 用于均匀加热非线性光学晶体装置的筒式加热器布置在散热器中,并且盒式加热器的温度由加热器控制器调节。 激光被输入到非线性光学晶体装置中,并且在其波长被转换成缩短波长之后被输送。 当激光的重复频率高时,停止加热器的加热,并利用散热器进行冷却。 当激光的重复频率低时,进行加热器的加热,以使非线性光学晶体装置的温度保持在转换效率令人满意的温度。
