With two cw single-mode Nd:YAG lasers at 1064 and 1319 nm and a periodically poled lithium niobate crystal, 11 mW of 2 kHz/100 ms bandwidth single-mode tunable 589 nm cw radiation has been detected using single-pass sum-frequency generation. The demonstrated conversion efficiency is ... [Opt. Lett. 34, 1093-1095 (2009)]

Passively Q-switched self-Raman laser oscillations in the SrMoO_4:Nd^3+ crystal optically pumped by a laser diode (LD) at 804 nm are demonstrated for the first time to our knowledge. Output parameters of LD-pumped SrMoO_4:Nd^3+ laser were investigated in free-running, passively Q-switched, and ... [Opt. Lett. 34, 1102-1104 (2009)]

The field of transparent ceramics is enjoying a renaissance, as refractory oxides are being developed as alternatives to single crystals in high-performance laser systems. However, a significant challenge remains regarding the reduction of the grain size to sufficiently subwavelength dimensions in ... [Opt. Lett. 34, 1033-1035 (2009)]

We demonstrate a robust optofluidic dye laser that integrates fluidics with a high Q-factor ring resonator. In this optofluidic laser the ring resonator is formed by an optical fiber fused on the inner surface of a glass capillary serving as a fluidic channel. Laser oscillation is achieved with a ... [Opt.

Wavelength-tunable multicolored femtosecond laser pulses were generated simultaneously through cascade four-wave mixing in a fused-silica glass plate using two crossing femtosecond laser beams. The wavelength of the sidebands can be continuously tuned from UV to IR. The pulse duration, spatial ... [Opt. Lett. 34, 1066-1068 (2009)]

We have fabricated BaO–TiO_2–GeO_2–SiO_2-based glass fibers with the oriented space-selectively crystallized structure by laser irradiation and also demonstrated variable optical attenuation induced by electro-optical birefringence change based on second-order optical ...

We report the generation of Bessel beams using polytetrafluoroethene conical lenses and a quantum cascade laser emitting at 2.8 THz. The formation of a central beam spot that retains its size over distances exceeding the characteristic Rayleigh range is demonstrated, and the power transport ... [Opt. Lett. 34, 1030-1032 (2009)]

We have measured magnetic fields up to 17.7 T with a rise time of 75 ns using temporally resolved Faraday rotation of a single longitudinal mode laser beam through a magneto-optically active bulk waveguide. We believe this to be the first time that such large, rapidly varying magnetic fields have ... [Opt. Lett. 34, 1009-1011 (2009)]

We demonstrated a fully fiber-integrated widely tunable picosecond optical parametric oscillator based on highly nonlinear fiber. The ring cavity with a 50 m highly nonlinear fiber was synchronously pumped with a picosecond mode-locked fiber laser. The tuning range was from 1413to1543 nm and from ... [Opt. Lett. 34, 989-991 (2009)]

Backward terahertz pulses were converted from ultrafast pulses of a laser amplifier within multiperiod periodically poled LiNbO_3 (PPLN) wafers. The average output powers of more than 2 μW were obtained from all six domain periods, corresponding to the frequency range of 217 GHz–2.373 ... [Opt. Lett. 34, 995-997 (2009)]
