Pulse Compression Gratings
High efficiency diffraction gratings for pulse compression
When ordering a pulse compression grating, please use the following example format, or choose from the PC grating stock list below.
PC 1200 W x H x Thk 800 nm (TM/-1) constant deviation <10°
PC stands for Pulse Compression grating
1200 is the groove density (groove frequency) in grooves/mm
W is the blank dimension in mm parallell with the grating grooves
H is the blank dimension in mm perpendicular to the grating grooves
Thk is the blank thickness in mm
800 nm is the desired optimised wavelength. A range or range with peaked wavelength can also be specified
(TM/-1) is desired polarisation state and diffraction order the grating should be optimised for. TE and average (TM+TE)/2 can also be specified
Constant deviation 10° is the configuration the grating should be optimised for. Constant incidence angle can also be specified
Standard tolerances on W, H: ± 0.2 mm, Thk ± 0.5 mm. CA > 90 % of each dimension.
Standard sizes: 25 x 25 x 6 mm, 30 x 30 x 6 mm, 30 x 64 x 10 mm, 30 x 110 x 16 mm, 50 x 50 x 10 mm, 50 x 110 x 16 mm, 58 x 58 x 10 mm, 64 x 64 x 10 mm, 90 x 90 x 16 mm, 110 x 110 x 16 mm, 100 x 140 x 20 mm, 120 x 140 x 20 mm
Materials: Gold coating (Au) standard for λ > 750 nm. ZKN7 standard substrate material, Zerodur (Z) as option.
