Using matrix optics theory of laser resonator and the heat insensitive condition of the laser resonator which contains compensatory lens and thermal lens,we gave out the corresponding relationship between the diopter of compensatory lens and the diopter of thermal lens.On this basis,we designed a heat insensitive laser resonator with a wide operating range.It uses electrical tuning liquid lens as compensation lens.According to the change of pump power,we can adjust the diopter of the liquid lens in order to make the laser resonator keeping heat insensitive during the pump range.
