Cooling assembly for laser active solid materials, laser system and method for cooling a laser active solid material

摘要

The arrangement (1) has a nozzle unit for loading laser-active solid body material i.e. laser crystal (2), with an aligned coolant beam (11) of liquid coolant (K) i.e. water. The nozzle unit has a nozzle (3) with an annular nozzle body and a flat jet-like nozzle opening (24), where breadth of the nozzle opening corresponds to thickness of the coolant beam. A holder (4) has a holding segment for holding the material. The holder is formed as a single-piece, and has holding bores (16), where the segment has two parallel side walls (17) that are arranged at a distance from each other. Independent claims are also included for the following: (1) a laser arrangement (2) a method for active cooling of laser-active solid body material.
