Femtosecond self-doubling optical parametric oscillator based on KTiOAsO4
(IEEE, 2003)We report a femtosecond intracavity-frequency-doubled optical parametric oscillator that employs a single KTiOAsO4 crystal for both parametric generation and frequency doubling. This device generates a yellow output beam ... -
Laser wavelength upconversion with optical parametric oscillators using simultaneously phase-matched crystals
(Bilkent University, 2002)In this thesis, we present our work on optical parametric oscillators that employ a single nonlinear crystal that is simultaneously-phase-matched for second-harmonic or sum-frequency generation in order to obtain frequency ... -
Nanosecond sum-frequency generating optical parametric oscillator using simultaneous phase matching
(Optical Society of American (OSA), 2005)We report a nanosecond sum-frequency generating optical parametric oscillator based on a single KTiOAsO4 crystal that is simultaneously phase matched for optical parametric generation and sum-frequency generation. Pumped ... -
Phase-matched self-doubling optical parametric oscillator
(Optical Society of America, 1997-03-01)We report a synchronously pumped intracavity frequency-doubled optical parametric oscillator that employs a single KTiOPO4 crystal for both parametric generation and frequency doubling. Both nonlinear processes are phase ... -
Phase-matched self-doubling optical parametric oscillator
(IEEE, Piscataway, NJ, United States, 1996)A new self-doubling optical parametric oscillator (OPO) uses a single nonlinear crystal for both parametric generation and frequency doubling. It is based on a KTiOPO4 (KTP) crystal pumped by a Ti:Sapphire laser operating ... -
Plane-wave dynamics of single crystal upconversion optical parametric oscillators
(Bilkent University, 1999)This thesis presents our investigation of the dynamics of single crystal up- conversion optical parametric oscillators (OPO’s). In these devices, parametric generation and sum frequency generation or second harmonic ... -
Plane-wave theory of self-doubling optical parametric oscillators
(Institute of Electrical and Electronics Engineers, 1998-03)This paper presents a theoretical analysis of self-doubling optical parametric oscillators (OPO's) where a single nonlinear crystal is used for both parametric generation and frequency doubling. In these devices, the ... -
A self-doubling optical parametric oscillator based on aperiodically-poled lithium niobate
(2001)A self-doubling optical parametric oscillator (SDOPO) having one-dimensional aperiodic grating structure based on a LiNbO3 crystal was constructed. The structure was designed to quasi-phase-match both second harmonic ... -
Simultaneous phase matching of optical parametric oscillation and second-harmonic generation in aperiodically poled lithium niobate
(Optical Society of American (OSA), 2003)We report a simple ad hoc method for designing an aperiodic grating structure to quasi-phase match two arbitrary second-order nonlinear processes simultaneously within the same electric-field-poled crystal. This method ... -
Wafer bonded capacitive micromachined underwater transducers
(2009)In this work we have designed, fabricated and tested CMUTs as underwater transducers. Single CMUT membranes with three different radii and 380 microns of thickness are fabricated for the demonstration of an underwater CMUT ...
