Furthermore, even if the intensity of the excitation light fluctuates and the position of the equicrosstalk moves, the amount of heat supplied to the temperature controller will change in response to the fluctuation of the excitation light, so the thermal balance at the interface between the laser medium and the peripheral wall will be affected.

Similar to the operation of the conventional example, the part of the energy from the excitation light absorbed by the laser medium (1) during laser oscillation, which does not contribute to laser oscillation, is converted into thermal energy and generates heat within the laser medium (1). Since the heat is cooled by the coolant circulating in the flow path (5), the smooth surface (Le

The temperature controller (11) is in close contact with the
), the heat capacity determined by the material and volume of the peripheral wall (llb) and the amount of heat supplied from the circulating fluid of the pipe (lla) are set in advance, Non-smooth side surface (la) = (lb
), and the edges (lc) and (ld) of the laser medium (1) facing the circumferential wall (llb) are designed to have equal temperature distribution, so there is no mutual heat propagation effect.

By increasing or decreasing the amount of heat supplied to the temperature controller, thermal equilibrium is always maintained in the vicinity of the interface between the non-smooth side surfaces (la) and (lb) and the temperature controller (11).
