Wasatch Photonics’ enhanced volume phase holographic (VPH) gratings are exceptional for pulse compression and pulse stretching of high power ultrafast lasers. Their ultraclear transmissive gratings have the highest efficiency on the market, with virtually no ghosting or scatter. Unlike surface relief gratings, Wasatch Photonics gratings can be easily cleaned and handled. Choose from the range of stock gratings, or contact us to discuss custom OEM designs and materials. Wasatch Photonics is your partner, from small quantity prototyping through to volume production.

FEATURES AND BENEFITS

• Exceptional 1^st order diffraction efficiency
• High transmission over the full spectral band
• Low wavefront distortion, minimal scatter
• Uniform over the full clear aperture for minimal beam distortion
• Ideal for high pulse energy applications
• Robust design allows easy cleaning & handling
• Maximum optical design flexibility – ideal for folded designs

Many designers use transmissive pulse compression cavity designs for their flexible, compact, often folded layouts. Wasatch Photonics uniform efficiency, minimal scatter, and low wavefront distortion ensure they get the shortest, cleanest pulses.

OEM SOLUTIONS

Wasatch Photonics understands the processes & metrology needed to manufacture high quality pulse compression gratings in volume, at wavelengths up to 2500 nm. They work collaboratively with their OEM partners on each design and test procedure, establishing customer-specific test fixtures at their site to reduce the burden of inbound testing at your site for guaranteed system-ready performance. Wastch Photonics custom gratings can be tailored in small batches and large volumes alike, with line frequencies of 150 – 5000 lines/mm and bandwidths up to 800 nm. They support optical intensities up to 300 GW/cm² (100-200 fs pulses, <50 W systems) or up to several kW/cm² (continuous wave).
