Grating-based polarizer for Ti:sapphire wavelengths.

For high energy, ultrafast laser applications, common polarizer technologies used for variable attenuation do not fulfill the complete set of requirements to extinction ratio, transmission level, bandwidth, transmitted wavefront distortion, GDD ripple and energy handling capability. For these applications, and initially developed solely for Ti:sapphire wavelengths, Ibsen offers a unique, grating-based polarizer. The polarizer is 100% fused silica, with the polarizing grating being a surface relief, etched grating structure with no thin-film coatings of any kind.
