VPH Gratings
Ultrafast Laser Gratings

Kaiser Optical Systems, Inc. (KOSI) has developed its volume phase holographic (VPH™) transmission gratings to support the ultrafast laser community. VPH gratings with very high diffraction efficiency covering the entire spectral bandwidth are ideal for use as the critical dispersion elements and allow laser pulses to be compressed into the femtosecond regime. A VPH transmission grating exhibits very low loss and low scatter. Each VPH grating is encapsulated between two glass substrates with anti-reflection coatings applied to the external surfaces. This results in a robust physical package that will withstand typical handling and can be cleaned with the same techniques used on high quality lenses.

KOSI's VPH transmission gratings are found in ultrafast lasers deployed around the world for various uses from human eye surgery to ultra fine micro machining of metals.With more than 20 years of experience designing and fabricating high quality holographic optics KOSI has established itself as a leader in VPH grating production for ultrafast laser use.
