Problems solved by technology

However, the disadvantage of the single-stage laser of this structure is: the output power is small, and the laser cutting machine equipped with this single-stage laser has a slow cutting speed and a shallow cutting depth. It is generally used for cutting within 2mm, such as: for drilling Superhard materials such as diamond polycrystalline (PDC) composite sheet and cubic boron nitride polycrystalline

Abstract

The invention discloses a laser, with high output power and good quality of beams for cutting, is applied to laser cutters. The laser comprises an oscillation stage which consists of a lamp pump cavity, a holophote and an output mirror, wherein the holophote and the output mirror are respectively arranged at the two sides of the lamp pump cavity; the external side of the output mirror is also provided with an amplifying stage which consists of a coupling mirror close to the output mirror and another lamp pump cavity. The laser has the advantages that the laser of the structure has high output power and good quality of beams for cutting; the laser cutter with the laser of the structure has quick cutting rate and deep cutting depth, for instance, 5mm cutting depth for PDC composite plates for drilling while 8mm cutting depth for cubic boric oxide polycrystal.

Description

technical field [0001] The invention relates to a laser cutting machine, in particular to a laser used in the laser cutting machine. Background technique [0002] Existing lasers used on laser cutting machines are generally single-stage lasers. Single-stage lasers generally consist of only one oscillation stage. The oscillation stage is commonly known as a resonator. The resonator is composed of a lamp pump cavity and a lamp pump cavity Composed of total reflection mirrors and output mirrors on both sides, the single-stage laser with this structure is used on laser cutting machines, and is generally used together with the beam expander focusing system installed on the laser cutting machine. The beam expander focus system is set near the output mirror. On the one hand, the working principle of the laser cutting machine equipped with this single-stage laser is: the laser light generated by the single-stage laser first passes through the beam expander focusing system to expand ...
