PPC Technology Enables Better Disk Lasers

PPC’s manufacturing technology has now been proven to enable higher performance disk and thin-disk solid state lasers. These high-performance bonded structures for solid-state laser amplifiers and oscillators use Precision Photonics’ proprietary CADB™ epoxy free bonding process and high energy ion beam sputtered coatings to achieve composite crystal, glass, or ceramic structures. With these processing technologies, PPC has been able to produce disk laser structures with lower transmitted wavefront distortion, better cooling characteristics, and higher fluence handling capabilities. This is obviously ideal for high-power solid-state laser applications in both defense/aerospace and materials processing, or where excellent beam quality and high power is needed.

In addition to disk laser configurations, PPC can fabricate devices in a variety of geometries (rod end caps, slabs and disks) and form factors from 1 mm to greater than 100 mm. The CADB process is extremely strong and offers negligible scatter and absorptive losses at the interfaces. Our ion beam sputtered coating technology can handle damage thresholds above 40 J/cm² with less than 2 ppm bulk absorption in the coatings.

Femtosecond mirrors

Our Ion Beam Sputtered (IBS) coatings are ideal for high intensity, ultra-short beam control. Our process repeatably produces coatings with properties matching the theoretical design. This enables us to produce coatings with complex layer thicknesses. One such application is dispersion controlled mirrors for fs applications. Not only can we achieve low Reflected Group Delay Dispersion (GDD), we can also achieve negative GDD mirrors. One such design is shown below for a normal incident mirror with a –20 fs² GDD over ~150nm bandwidth. We offer standard dispersion managed mirrors, and can provide custom coatings and components to meet your requirements.
