Pegasus Pockels Cells
From the leader in nonlinear materials and electro-optic devices comes the Pegasus Series pockels cells designed for high speed as well as infrared application.
Full Product DescriptionProduct description
Pegasus pockels cells use exceptionally high quality Lithium Niobate crystals (LiNbO3) crystals that are grown and fabricated by G&H, insuring high extinction ratio, high transmission, low switching voltage, and excellent temperature stability.
Thanks to our vertical integration, we have full end-to-end quality control from crystal growth and polishing to our extensive range of in-house AR coatings.
The unique capabilities of Pegasus makes it a higher performance alternative to RTP based Pockels cells for Q-switching high energy mid-IR lasers such as, Er:YAG 2.94 µm, Er,Cr:YSGG 2.79 µm, Ho:YAG 2.10 µm and Tm:YAG 2.01 µm. Pegasus is the ideal Pockels Cell choice for commercial applications in, for example, aesthetic and ophthalmic surgery and military applications, including target designation and range finding.
