  • We describe a technique for generating tunable narrow-band terahertz radiation via optical rectification in periodically-poled lithium niobate. Frequency tuning is accomplished by spatially chirping the domain width laterally to the beam propagation direction, and adjusting the temperature of the sample. We demonstrate tuning over a continuous range from 0.8 to 2.5 THz. The bandwidth of the terahertz waveforms is as narrow as 0.02 THz. {copyright} 2001 American Institute of Physics.
  • We report kilohertz repetition-rate pulse-to-pulse wavelength tuning from 3.22 to 3.7 {mu}m in a periodically poled lithium niobate (PPLN) optical parametric oscillator (OPO). Rapid tuning over 400thinspcm{sup {minus}1} with random wavelength accessibility is achieved by rotation of the pump beam angle by no more than 24thinspthinspmrad in the PPLN crystal by use of an acousto-optic beam deflector. Over the entire tuning range, a near-transform-limited OPO bandwidth can be obtained by means of injection seeding with a single-frequency 1.5-{mu}m laser diode. The frequency agility, high repetition rate, and narrow bandwidth of this mid-IR PPLN OPO make it well suited as amore » lidar transmitter source. {copyright} {ital 1999} {ital Optical Society of America}« less
  • Here, the preferential deposition of metal nanoparticles onto periodically poled lithium niobate surfaces, whereby photogenerated electrons accumulate in accordance with local electric fields and reduce metal ions from solution, is known to depend on the intensity and wavelength of the illumination and the concentration of the solution used. Here, it is shown that for identical deposition conditions (wavelength, intensity, concentration), post-poling annealing for 10 h at 200 °C modifies the surface reactivity through the reorientation of internal defect fields. Whereas silver nanoparticles deposit preferentially on the +z domains on unannealed crystals, the deposition occurs preferentially along 180 degrees domain wallsmore » for annealed crystals. In neither case is the deposition selective; limited deposition occurs also on the unannealed -z domain surface and on both annealed domain surfaces. The observed behavior is attributed to a relaxation of the poling-induced defect frustration mediated by Li + ion mobility during annealing, which affects the accumulation of electrons, thereby changing the surface reactivity. The evolution of the defect field with temperature is corroborated using Raman spectroscopy.« less
  • For what is believed to be the first time, a single-longitudinal-mode passively Q -switched Nd:YAG microlaser is used to pump a narrow-bandwidth periodically poled lithium niobate (PPLN) optical parametric generator-optical parametric amplifier (OPG-OPA). Before amplification in the OPA, the output of the OPG stage was spectrally filtered with an air-spaced etalon, resulting in spectroscopically useful radiation (bandwidth, {approx}0.05 cm{sup -1} FWHM) that was tunable in 15-cm{sup -1} segments anywhere in the signal range 6820-6220 cm{sup -1} and the idler range 2580-3180 cm{sup -1} . The ability to pump an OPG-OPA with compact, high-repetition-rate, intrinsically narrow-bandwidth microlasers is made possible bymore » the high gain of PPLN. The result is a tunable light source that is well suited for use in portable spectroscopic gas sensors. (c) 2000 Optical Society of America.« less
  • We present theoretical predictions and experimental results of a mid-infrared optical parametric oscillator (OPO) based on periodically poled lithium niobate. An air-space intracavity etalon causes our OPO to oscillate on a single longitudinal mode. Continuous frequency tuning of this mode is achieved by simultaneous adjustment of the etalon mirror spacing and the OPO resonator length with piezoelectric translators. We achieved 10 cm-1 of continuous frequency tuning and more than 10 cm-1 of mode-hop tuning. The OPO is pumped with 200 {mu}J/pulse by a seeded, 1-kHz, Q-switched Nd:YAG laser and provides as much as 10 {mu}J of energy in both themore » idler near the 3-{mu}m wavelength and in the signal near the 1.6-{mu}m wavelength. We obtained a resolution of 0.01 cm-1 with the idler when measuring the spectrum of the Q branch of the methane C-H stretch under Doppler-limited conditions. (c) 2000 Optical Society of America.« less
