Abstract

Temperature change affects the output power of DPL remarkably.A real-time temperature control technique is presented which can keep the laser crystal and Q-switched working at the setting temperature under any environment conditions based on TL494 pulse width modulator used to control the temperature.The technique has been used in Nd:YVO4 LD-pumping laser and got stable output power,which proves it is stable and reliable.
