FIELD: laser tools.

SUBSTANCE: invention relates to laser cutting head (1) and laser cutter. Head (1) comprises housing (5), laser radiation source (3) located at first end (4) of housing (5), nozzle (6) located on other end (7) of housing (5), optical system (8) located inside housing (5) between source of laser radiation (3) and nozzle (6). Elements of optical system (8) are fixed relative to each other. Housing (5) comprises at least two parts (10, 11), which can move relative to each other such that due to mutual displacement position of laser radiation source (3) and/or nozzle (6) and/or optical system (12) can vary, so that the geometry of laser beam (9) inside housing (5) can be changed during use to achieve the required focusing parameters of laser beam (9) on the surface of workpiece (27). Elements of optical system (8) are combined with second part (11) of housing (5).

EFFECT: head for laser cutting and laser cutter containing such head are proposed.
