US Patent:

7852549, Dec 14, 2010

Filed:

Jul 31, 2008

Appl. No.:

12/184199

Inventors:

Theodore Alekel - Portland OR, US
David A. Dutton - Corvallis OR, US
David H. Foster - Corvallis OR, US
Joseph G. LaChapelle - Philomath OR, US
Michael J. Munroe - Eugene OR, US

Assignee:

Deep Photonics Corporation - Vancouver WA

International Classification:

G02F 1/35
G02F 2/02

US Classification:

359328, 359326, 372 22, 372 97, 372105

Abstract:

An apparatus for producing coherent, pulsed ultraviolet light with pulse durations that range between 1 ps and 1 μs includes one or more source lasers in the visible or near-infrared frequency range. The apparatus also includes one or more FC stages, at least one of the one or more FC stages including a nonlinear FC device and one or more optical elements. The optical elements include a reflector, a focusing element, a polarization-controlling optic, a wavelength separator, or a fiber optic component. The FC device includes a huntite-type aluminum double borate nonlinear optical material configured to produce FC light having a wavelength between 190 and 350 nm and a composition given by RAlBO, where R comprises one or a plurality of elements {Sc, La, Y, Lu}. The nonlinear optical material is characterized by an optical transmission greater than 70% over the wavelength range of 190 to 350 nm.
