Profile: AdvR, Inc. specializes in optical devices and systems using engineered bulk and waveguide nonlinear optical materials. Our product line includes custom KTP waveguides, frequency conversion modules, 100 ps pulsed diode laser, electro-optic fiber switch and electro-optic modulators. Our 1064 nm 100 ps pulsed diode laser emits 1 watt peak power in 125 ps with a user-controlled pulse repetition rate of 100 Hz-25 kHz, that maintains narrow spectral bandwidth (<0.5 nm at 25 dB below peak emission). The laser output via single mode PM fiber is terminated with an FC/APC connector for ease of system integration. Our KTP waveguide is a nonlinear optical material that can be used for a variety of frequency conversion applications (both type I and II), Bragg stabilization, and phase modulation. We provide custom manufacture waveguides, & are able to create multi-element waveguides with multiple interactions per waveguide. We also offer fiber packaged options for our waveguides. It is featured with quantum key detection(QKD), type I and II upconversion at 400 nm form entangled photon research, & efficient SHG throughout the visible spectrum (400-800 nm).
