PPLN Crystal
Periodically poled lithium niobate (PPLN) is a kind of nonlinear crystal with high efficiency of wavelength conversion. It has a wide light transmission range of 0.4-4.5 μ m, covering the near and mid infrared regions, and has a long service life. It can be used for frequency doubling, difference frequency, sum frequency, optical parametric oscillation and optical parametric amplification, etc OPO process can obtain 3 ~ 4.5 μ m wavelength of light, which can realize the band where conventional phase matching is difficult to achieve efficient output. Different wavelengths of PPLN correspond to different polarization periods UV-IR T: 0.5-5mm Description | Value Type of conversion | SHG、DFG、SFG、OPO、OPA、OPG, etc. Grating type | Grating type QPM period | Standard and customized(4.0um~200um) Wavelength | 330nm~5500nm Matching temperature | 25℃~200℃ Size | Standard and customized Duty | 48%~52% or customized Flatness | ?/6@632.8nm Parallelism | <10” Perpendicularity | <10’ Surface Quality | 10-5 Coating | AR/HR

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
