PROBLEM TO BE SOLVED: To obtain a solid laser apparatus capable of fixing a laser medium so that the medium cannot move, and reducing distortion in laser operation. SOLUTION: The solid laser apparatus is provided with a thin plate-like laser medium 1 for absorbing an excitation light to generate a gain, a heat sink 3 for discharging heat of the laser medium 1 to the outside, and a bonding agent 2 for bonding the laser medium 1 to the heat sink 3. The apparatus has a relation of Ts≥Td≥Th and a relation ofα(Ts-Td)≈η(Ts-Th), whereαis a linear expansion coefficient in a junction surface of the laser medium 1,ηis a linear expansion coefficient of the heat sink 3, Ts is a curing temperature of the bonding agent 2, Td is an operation temperature of the laser medium 1, and Th is an operation temperature of the heat sink 3.
