UV laser series (L9500-S3W/S5W, F3W/F5W) Product introduction
Ultraviolet laser is the use of frequency doubling technology to obtain the second harmonic and then use the sum frequency technology to obtain ultraviolet laser spectrum, crystal frequency doubling can achieve continuous ultraviolet laser, its beam shape is Gaussian, so the spot is circular, energy gradually decreases from the center to the edge.Due to the short wavelength and beam quality limitations, the beam can be focused in the order of 10 mm.
Ultraviolet laser is from the core 808nm wavelength module through a frequency doubling crystal to 1064nm wavelength, through a frequency doubling crystal wavelength to 532 green, through a frequency tripling crystal wavelength to 355 violet, that is, the use of ultraviolet laser working process.Its crystal belongs to the important part of ultraviolet laser, plays the role of frequency doubling wavelength, the normal use time of crystal is 12000 hours.When the crystal reaches the upper limit of use, it will produce cracks and cannot be multiplied, so that the laser has no energy and cannot mark obvious effects on the surface of the product.
