Gratings exhibit high diffraction efficiency
Wasatch Photonics has released the patented Dickson 1450 l/mm volume phase grating for laser pulse compression and other applications
These gratings exhibit a high diffraction efficiency greater than 90% at the centre wavelength of 1030nm. These Dickson gratings are exposed holographically, using well-collimated laser light in dichromated gelatin resulting in low scatter, high diffraction efficiency, high dispersion, and low wavefront distortion.

Because they are protected between two pieces of glass, they can be cleaned using the same methods used to clean AR coated lenses and prisms.
The Dickson 1450 l/mm grating has been added to Wasatch's stock product-line.
The stock gratings are available in 25 x 25 x 6mm, which are produced on fused silica substrates.
In addition, these gratings have a wavefront quality of 1/10 wave RMS at 633nm transmitted over the clear aperture.
The Dickson 1450 l/mm gratings are also available in a wide range of custom sizes.
