The invention relates to a
temperature control method of
laser medium of a
disk laser and a device thereof. The method comprises the steps that
temperature control is performed on
laser medium in different regions through a
semiconductor refrigerating
chip array; firstly reference temperature is set,
laser medium subregions, the temperature of which is higher than the reference temperature, are refrigerated, and laser medium subregions, the temperature of which is lower than the reference temperature, are heated; the device comprises the laser medium, a
heat sink connected with the laser medium, heat-conducting glue, a temperature sensor on the heat-conducting glue, the
semiconductor refrigerating
chip array, a closed-loop circuit
control system and a computer
system; the temperature sensor detects the practical temperature of the laser medium subregions in real time, sends the practical temperature to the computer
system, and sends
temperature control signals after the practical temperature is compared to the reference temperature; and a closed-loop circuit feeds back the temperature control signals to
semiconductor refrigerating chips in real time, so as to realize the real-
time control to the laser medium subregions, and to realize the
bulk temperature control to the laser medium. The method can dynamically control the temperature of the laser medium to be evenly distributed, and effectively restrain the problem of the
thermal effect of the laser medium.
