VPH gratings from Kaiser Optical

Kaiser Optical Systems Inc. announced it has developed a line of pulse compression gratings for ultrafast laser applications.

The company has developed its volume phase holographic (VPH) transmission gratings to support the ultrafast laser community. VPH gratings have a high diffraction efficiency and are suitable for use as the critical dispersion elements that allow laser pulses to be compressed into the femtosecond regime.

A VPH transmission grating exhibits low loss and low scatter. Each VPH grating is encapsulated between two glass substrates with antireflection 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.
