PPC broadband prism polarizers offer low GVD

This low group-velocity dispersion (GVD) prism polarizer for broadband femtosecond applications uses the company's advanced ion-beam-sputtering (IBS) coatings and a CADB epoxy-free bonding technique to provide low loss. The prism maintains a >2000:1 extinction ratio from 700–1100 nm without sacrificing overall transmission (Tp > 96%) or damage threshold (initial testing to >10 J/cm²). Applications include regenerative amplifiers and optical isolators for ultrafast lasers, optical coherence tomography (OCT), microscopy, and imaging.

PRESS RELEASE

PPC Introduces Low GVD, Broadband Polarizers (700-1100nm)

BOULDER, Colorado (April 21, 2011): Precision Photonics Corporation (PPC), a leading provider of ultra-precise optics and opto-mechanical assemblies, announces a new low dispersion, high energy polarizer for broadband femtosecond applications. Like our selection of laser-line polarizing beamsplitter cubes and beam combiners, these components utilize PPC’s advanced ion-beam-sputtering (IBS) coatings and Telcordia-qualified CADB® epoxy-free bonding technique to provide unique, low-loss optical components without compromising critical performance attributes – broad bandwidth, excellent wavefront quality, high extinction ratio, high transmission, low dispersion and high LDT.

This low GVD broad-band polarizer maintains a > 2000:1 extinction ratio from 700-1100nm without sacrificing overall transmission (Tp > 96%) or damage threshold ( initial testing to >10J/cm2!). These fused silica beam splitters will be offerred with a standard ½” x ½” input face, and custom prism polarizers will be available in sizes from 1mm to > 20mm. Applications include regenerative amplifiers and optical isolators for ultrafast lasers, optical coherence tomography, microscopy, and imaging.

The innovative shape of the prisms allows ultra-broadband pulses to travel in and out of the polarizer without refraction, thus avoiding spatial dispersion of the broadband pulse (prism effect). The multi-dimensional, advanced performance of the Low GVD Prism Polarizer is not possible with typical cube beam splitters, calcite prism polarizers or thin film plate polarizers.
