Introduction of the 1060nm Nd:Glass laser for material processing

 Let’s learn about the 1060nm Nd:Glass laser for material processing

The 1060nm Nd-doped phosphate glass laser has essential material processing applications and may be used for laser drilling and welding. Pump light is easily absorbed because Nd Glass has a long fluorescence lifespan, a strong energy storage property, a wide absorption spectral bandwidth, and a low heat conductivity of the glass foundation.

Theory

Laser Glass - Nd:Glass

Nd doped glass has good optical performance, high energy conversion efficiency, is easy to process and low cost, and is suitable for Q-switching. It was used to make a 1060nm laser. The downside is that the thermal conductivity isn't as good as ruby's, and the temperature impact isn't as strong. As a result, adopting a complete water cooling system can still improve stability.

Passive Q-switch - Cr:YAG

Cr4+ YAG is a crystal that is utilized in lasers for passive Q-switchingand is a novel laser crystal. It may be used in the wavelength ranges of 900-1200 nm and 1350-1600 nm, making it suitable for Nd doped glass.

Pump light

The xenon lamp's radiation spectrum contrasts with the absorption spectrum of Nd glass, and the two have a good consistency, making the xenon lamp a good light pump.

Focus Cavity

The focus cavity's outside walls are machined into evenly spaced grooves to lower the cavity's weight and enhance the heat dissipation area.

Optical cavity

For the 1060n m laser, a flat-faced cavity was employed, and the total reflection dielectric layer had a reflectance of 98 percent.

Cooling method

Deionized water is blasted into the focus cavity in a circular motion to cool the xenon lamp, the working material, and the focus cavity all at the same time.

Feature

High energy conversion efficiency

Good optical uniformity

Easy optical processing

low cost

Good energy storage effect

Application

Hardening Treatment

Laser welding

Laser Hole Drilling

Verdict

The Nd doped glass laser's output wavelength is 1060nm. The fundamental benefit of the neodymium glass laser is its cheaper cost and greater energy conversion efficiency, as well as the fact that it can be manufactured into bigger devices for higher power or Infrared pulsed lasers with more energy. Laser processing, such as punching and welding, is mostly done using this type of laser.

Pockels Cells Crystal

1. Pockels Cells Based on the electro-optic effect , when the applied electric area acts on the Pockels cell crystal ( electro-optic crystal ), the Pockels cell crystal (electro-optic crystal) is like a wave plate whose phase delay is related to the used electric field. The polarization state of the outbound light from the Pockels cell crystal will certainly change so that the strength as well as amplitude of the outbound light from the analyzer are regulated, which is electro-optic inflection, and the modulation tool is called a Pockels cell. 2. Pockels cell crystal The crystals that produce the electro-optical effect are called Pockels cell crystals, that is, electro-optical crystals. They each have their benefits. Presently, the major Pockels cell crystals on the marketplace consist of BBO crystals , DKDP crystals , KTP crystals , as well as LN (LiNbO3) crystals . (1) BBO crystal BBO crystal , additionally called barium metaborate crystal, chemical formula BaB2O4, is an electro-opt
