Single layer or multiplayer anti-reflecting or high-reflecting coatings
FOCtek Photonics, Inc. was established in Nov. 18, 2001, which is a joint venture company integrated in manufacturing, marketing and designing . Our products include Laser crystals, NLO crystals, ....
high birefringence, wide spectral transmission; availability in reasonably sized rhombs;
isolators, circulators and interleaver ect.
high optical homogeneity; high damage threshold; low hygroscopic susceptibility; extremely low absorption in the UV to IR range
The most popular retarders are quarter and half wave
has a length to aperture ratio less than 1.0 makes it a relatively thin polarizer.
used to split or combine two perpendicular polarization laser beam
Reflecting prisms may invert, rotate, deviate or displace a beam
high gain, low threshold, and high absorption coefficients at pumping wavelengths
large nonlinear optical coefficients; wide angular bandwidth ; small walk-off angle.
Wide transparency and phase matching ranges, large nonlinear coefficient
can be effectively pumped by short pulse flashlamps in powerful laser systems.
used in solid-state lasers systems-frequency-doubled continuous wave, high-energy Q-switched
high gain, low threshold, high absorption coefficients at pumping wavelengths
Micro PBS The Micro PBS separate a laser beams into two different polarization beams. The micro PBS is generally used in fiber optical communication as the core part of polarizer, polarization beam....
