Embodiment 1

[0036] see Figure 4 , 5 , The sheet laser module provided by the embodiment of the present invention includes: a pumping light source 1, a laser medium 2, a first cooling device 3 and a second cooling device 4 respectively arranged at both ends of the laser medium 2. Wherein, the laser medium 2 includes an undoped medium 21 and a thin gain medium 22 disposed at the bottom of the undoped medium 21 . The undoped medium 21 includes a frustum-shaped body 211, and two symmetrical planes (the first plane 212 and the second plane 213) are processed on the side of the body 211, and the pumping light and the Light-transmitting film with high transmittance for laser light. The sheet gain medium 22 is preferably bonded to the bottom of the body 211 using a chemical adhesiveless bonding technique. In addition, the bottom and top of the body 211 can be designed as circular stepped structures, ie, the top step 214 and the bottom step 215, so as to facilitate installation. further refer...

Embodiment 2

[0062] Figures 12 to 14 A schematic structural diagram of the thin-film laser module provided by the second embodiment of the present invention is shown.

[0063] Embodiment 1 provides a schematic structural diagram of a thin-chip laser module. For a laser system, it may include only one thin-chip laser module described above, or may include multiple thin-chip laser modules to realize power upgrade. This embodiment further provides a chip laser system formed by connecting multiple chip laser modules in series.

Abstract

The invention is suitable for the technical field of laser, and provides a thin disk laser module. The thin disk laser module comprises a pump light source, a laser medium, a first cooling device and a second cooling device, wherein the first cooling device and the second cooling device are respectively arranged at two ends of the laser medium; the laser medium comprises an un-doped medium and a thin disk gain medium which is arranged at the bottom part of the un-doped medium, the un-doped medium comprises a cone frustum type body, the side surface of the body is provided with a first flat surface and a second flat surface which are symmetrical about each other, and light transmitting films are plated on the first flat surface and the second flat surface; the first cooling device is provided with a first chamber, the second cooling device is provided with a second chamber, the first chamber is sealed by the thin disk gain medium, and the second chamber is sealed by the un-doped medium; pump light and laser light are subjected to total reflection when being emitted from the thin disk gain medium to cooling liquid. According to the thin disk laser module disclosed by the invention, the thin disk gain medium and the un-doped medium are directly in contact with the cooling liquid, no coating film is formed on the surface of the thin disk gain medium, the heat dissipation speed of the laser medium is increased, a thermal lens effect on the thin disk gain medium is removed, and the stability and the beam quality of a laser are increased.

Description

technical field [0001] The invention belongs to the technical field of lasers, in particular to a thin slice laser module and a laser system. Background technique [0002] All-solid-state laser (DPSSL, Diode pumped solid state laser) refers to a solid-state laser that uses a semiconductor laser (LD) as a pumping source. The gain medium and pumping source are all composed of solid materials, so traditional solid-state lasers and semiconductor The advantages of a laser all in one. It has the advantages of small size, light weight, high efficiency, stable performance, good reliability, long life, easy operation, flexible operation (continuous operation, pulse operation), easy intelligence, and no pollution. It is the most potential laser at present. one of the sources. [0003] Flake lasers are a type of all-solid-state lasers. Such as figure 1 , the thin sheet gain medium 1 in the existing thin sheet laser generally adopts a thin sheet-shaped material with a small thicknes...
