Sapphire Waveplates to 3.5 µm
PPC is now manufacturing custom multiple-order, true zero-order and compound zero-order waveplates from 266 nm to 3.5 µm. These components can be made in a variety of shapes with retardations of quarter-wave, half-wave or anything in-between. UV-IR waveplates are available using laser grade crystal quartz or sapphire materials and as stand-alone components, or as part of a more complex optical assembly. Durable, high-energy anti-reflection coatings are provided using PPC’s ion beam sputtering process to maximize transmission, laser damage threshold and environmental stability.

In addition to disk laser configurations, PPC fabricates devices in a variety of geometries (rod end caps, lasers slabs and waveguides) and in 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.

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.
Low-loss AR Coatings with R <0.05%
In addition to a variety of off-the-shelf laser optics, PPC offers custom high-energy coating designs from 266 nm to 3500 nm. We use ion-beam sputtering (IBS) technology because IBS is a repeatable process that can be precisely controlled, resulting in well-centered, highly efficient coatings such as the anti-reflection (AR) coating shown here with reflectance <0.05% at 1064 nm.
