FIELD: laser equipment.
SUBSTANCE: invention relates to laser engineering and compression-cooled fibre lasers. Compression-cooled fibre laser comprises a housing accommodating an optical portion, a cooling device; optical part is mounted on a cold plate; housing has two inner spaces in which an optical part and a cooling device are located; cold plate includes a coolant pipeline connected to the coolant pipeline of the cooling device for circulation of the coolant, wherein the cold plate is a flat panel structure with buried tubes, on the surface of which a semiconductor laser is installed, cold plate is installed vertically on the inner side of the laser housing, and the second surface of the cold plate serves as an interface between the first inner space and the second inner space.
EFFECT: heat removal without detriment to laser stability.
