Strong long-period fiber gratings recorded at 352 nm

Autor: Dubov, Mykhaylo, Bennion, Ian, Slattery, Stephen A., Nikogosyan, David N.

We describe long-period grating inscription in hydrogenated telecom fibers by use of high-intensity femto-second 352 nm laser pulses. We show that this technique allows us to fabricate high-quality 30 dB gratings of 300 μm period and 2 cm length by

Nonlinear optical crystals: a complete survey

Autor: Nikogosyan, David N

Nonlinear optical crystals are widely used in modern optical science and technology for frequency conversion of laser light, i.e. to generate laser radiation at any specific wavelength in visible, UV or IR spectral regions. This unrivalled reference
