CRYLINK provides various types of high-power X/Y scanning mirrors, mainly including silicon scanning mirrors and quartz scanning mirrors, for laser scanning mirror systems above 6Kw. Laser wavelengths include 355nm, 532nm, 1064nm, and 10.6μm.

Description

Thanks to the special coating technology, it is possible to ensure that the mirror dissipates heat quickly and with little temperature rise at the laser focus during use. The amount of change in the shape of the used surface is very small. The mirror has a high threshold of laser damage, which can meet the requirements of long-term stable use of the scanning mirror.

High-Quality Substrate

· High-quality substrate material, rough machining, and polishing quality are the main factors affecting the performance of optical elements.

· The mirrors are made of imported Corning 7979 and 7980 materials with guaranteed quality;

· For high-power laser optical elements, it is particularly required that the edge collapse of the substrate should be well controlled, otherwise the mirror's film will crack and extend in the process of use.

· The surface finish and roughness of the substrate will greatly affect the damage threshold of the film.

· The surface shape of the substrate will affect the shape of the laser spot, so PV and RMS need to be controlled.

High Coating Quality

· Good reflectivity of the lens under different incident angles.

· Under different incident angles, the reflectivity of the probe light is high enough.

· After coating, the deformation of the substrate should be small enough. The stress relief design of the film must be considered.

· Good laser damage threshold.

Verdict

CRYLINK’s laser scanning mirror products have high-quality polished substrates, low residual stress in the film layer of the lens after coating, and good surface shape.

By applying electric field control to the electro-optic crystal, the refractive index of the electro-optic crystal in a certain direction can be changed, so that the Pockel unit of the electro-optic modulator can be used as a variable half wave plate to change the polarization state. The wave Kerr unit of the electro-optic modulator is placed between two vertical polarizers to realize light intensity modulation. Electro optic effect can be divided into transverse electro-optic effect and longitudinal electro-optic effect. In the transverse electro-optic effect, the propagation direction of light is perpendicular to the electric field, while in the longitudinal electro-optic effect, the propagation direction of light is parallel to the electric field.

CRYLINK’s pockels cells use protective windows with high-quality AR coating, which can ensure a high transmission rate and prolong the service life of the device.

The half-wave voltage of the longitudinal electro-optic effect is independent of crystal size, so it is difficult to realize high-frequency electro-optic modulation. The working principle of BBO pockels cells is based on transverse electro-optic effect, the half wave voltage can be reduced by changing the size of BBO crystal. Crylink can provide BBO pockels cells with different aperture and lengths, which can adapt to different environments. Due to its low ringing effect and high laser-damaged threshold, the maximum frequency of Crylink’s BBO pockels cells can reach 1MHz.

Verdict

CRYLINK can provide BBO pockels cells with different aperture and length that have the features of low ringing effect, small size, light weight, and high laser-damaged threshold.

UV laser is ultraviolet 355nm laser beam outgoing wavelength. It’s solid state laser source, and cold beam. Therefore, the heat affected zone will not bring about heat effect. Then material no deforming or burning. 

So UV laser has high beam quality and small spot. Especially, the processing of heat affected area is small. Currently UV laser engraving machine most used for ultra-fine marking, special material engraving and cutting. 

Compare with fiber and CO2 laser marking systems, uv laser marking machine beam spot is the smallest. Therefore, it can engrave any mini area. For example, UV laser engraving mobile, cutting LCD, or process medical precision materials, etc. 

 As video shows, UV laser marking numbers, QR code, logos, and other texts on the camera. This is a high-end smart camera. It's special used for Japanese market. As a result, uv laser marking effect better than fiber laser. 

With the quickly development of economic, the demand of people has become more and more personal. Therefore, the growing need of market for products that yield a high added value, multiple kinds and small quantity. So many manufacturers use automated laser marking system on assembly line.
