A medical laser system includes a crystal-based laser, a power supply for powering the crystal-based laser, a controller operably connected to the crystal-based laser and the power supply, and a liquid cooling system. The liquid cooling system includes a conduit circuit through which a cooling liquid can circulate. The conduit circuit is thermally coupled to the crystal-based laser such that the cooling liquid in the conduit circuit absorbs heat from the crystal-based laser. One or more heat sinks are coupled to the conduit circuit and to the power supply such that the cooling liquid in the conduit circuit absorbs heat from the power supply. A pump is provided for driving the cooling liquid through the conduit circuit. A heat exchanger cools the cooling liquid in the conduit circuit.
