Transient Thermal Characteristics of Heat Capacity High Power Diode Lasers
To investigate the application of heat capacity high power diode lasers under the condition of low temperature
high transient power and long interval working time
a 3-D transient thermal model was established. By adopting the finite element analysis
the effect of 3-D sizes of the heat sink on the transient thermal characteristics of diode laser was calculated successfully. According to the simulation results
the heat sink with dimension of 26.6 mm11.5 mm4 mm was chosen to package the heat capacity diode laser
and the experiments of the diode laser working 3.5 s continuously under -20 ℃ and -30 ℃ were carried out respectively. Eventually
the temperature curves of the active region were obtained and demonstrated a good consistence with the simulation results.
