Gratings for Laser Pulse Compression

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

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

OEM SOLUTIONS

At Wasatch Photonics, we understand the processes & metrology needed to manufacture high quality pulse compression gratings in volume, at wavelengths up to 2500 nm. We work collaboratively with our OEM partners on each design and test procedure, establishing customer-specific test fixtures at our site to reduce the burden of inbound testing at your site for guaranteed system-ready performance. Our 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. We support optical intensities up to 300 GW/cm² (100-200 fs pulses, <50 W systems) or up to several kW/cm² (continuous wave).
