Abstract

The optical properties of high power laser diode beam quality, intensity, life time and reliability of operation it dependent on the thermal operation of laser diode. In this research was tested the effective of thermal properties on the optical properties of high power laser diode when operated in long pulse mode and repetition rate, it available with on important application to pumping solid state lasers. The results obtained, the figure of emitters is approximately linearity with increased the temperature and current of laser diode, so the center of wavelength is variation with increased temperature about ( 2nm /100mA) and the increased in width of pulse lead to deceased the life time of laser diode is about ( 5000h at 300μs).
