体積型ホログラフィックブラッググレーティングフィルター.png

Volume holographic Bragg grating filter

Using VHG and VBG ultra-narrow band filters! Stabilization and narrowing of laser spectral light are performed.

Coherent VHGs are solid-state diffraction-type holographic filters made from unique photosensitive optical glass, providing ultra-stable, degradation-free performance throughout the filter's lifespan, unlike thin film films or gels. They are suitable for the removal of ASE in THz-Raman spectroscopy systems, fixing laser wavelengths, and Rayleigh blocking. If you are unsure which product is suitable, please contact us. 【Features】 ■ Stable wavelength control - Locks excitation/diode lasers over a wide temperature range ■ Narrow bandwidth - Enhances ASE and Rayleigh removal to maximize the performance of the spectroscopic system ■ Chirped pulse amplification - Extends and recompresses high-power CPA pulses in an ultra-compact size *For more details, please refer to the PDF document or feel free to contact us.
