“…The usefulness of sum-frequency generation to produce tunable UV radiation from nanosecond solid-state laser sources was demonstrated by several authors for alexandrite lasers [5][6][7], Ti:sapphire lasers [8][9][10][11][12][13][14], Cr-doped colquiriite lasers [15], or OPOs [16][17][18][19][20] in the past. However, none of the reported configurations would be able to fulfill the requirements of a laser for a compact, versatile ion mobility spectrometer.…”

We report on a compact, tunable ultraviolet laser system that consists of an optical parametric oscillator (OPO) and a longitudinally diode-pumped Nd:YAG master oscillator-power amplifier (MOPA). The pump energy for the whole laser system is supplied via a single delivery fiber. Nanosecond pulses are produced by an oscillator that is passively Q-switched by a Cr(4+):YAG crystal. The OPO is pumped by the second harmonic of the Nd:YAG MOPA. Continuously tunable radiation is generated by an intracavity sum-frequency mixing process within the OPO in the range of 245-260 nm with high beam quality. Maximum pulse energies of 1.2 mJ were achieved, which correspond to an optical efficiency of 3.75%, relating to the pulse energy of the MOPA at 1064 nm.

“…This laser has a wide tuning range from about 700 to 900 nm, which can be frequency doubled into the UV, 350−450 nm, by use of second harmonic generation techniques. This still leaves large gaps in the visible and UV that can be filled only by use of further doubling and mixing techniques, Raman shifting, and/or optical parametric frequency conversion . A laser system based on a titanium:sapphire laser with full tunability throughout the UV and visible is likely to be complex and expensive.…”

Characterization of a Tunable Optical Parametric Oscillator Laser System for Multielement Flame Laser Excited Atomic Fluorescence Spectrometry of Cobalt, Copper, Lead, Manganese, and Thallium in Buffalo River Sediment

A pulsed (10 Hz) optical parametric oscillator (OPO) laser system based on beta-barium borate (BBO) crystals and equipped with a frequency-doubling option (FDO) was characterized for use in laser excited atomic fluorescence spectrometry (LEAFS). This all-solid-state laser has a narrow spectral line width, a wide spectral tuning range (220-2200 nm), and a rapid, computer-controlled slew scan of wavelength (0.250 nm s-1 in the visible and infrared, and 0.125 nm s-1 in the ultraviolet). The output power characteristics (15-90 mJ/pulse in the visible, 1-40 mJ in the infrared, and 1-11 mJ in the ultraviolet), laser pulse-to-pulse variability (3-13% relative standard deviation, RSD, of the laser pulses), conversion efficiency of the FDO (2-17%), and spectral bandwidth in the visible spectrum (0.1-0.3 cm-1) were measured. The laser was used as the excitation source for a flame LEAFS instrument for which rapid, sequential, multielement analysis was demonstrated by slew scan of the laser. The instrument allowed about 640 measurements to be made in about 6 h, with triplicate measurements of all solutions and aqueous calibration curves, which yielded accurate analyses of a river sediment (National Institute of Standards and Technology, Buffalo River Sediment, 2704) for five elements with precisions < 5% RSD. Comparable or improved flame LEAFS detection limits over literature values were obtained for cobalt (2 ng mL-1), copper (2 ng mL-1), lead (0.4 ng mL-1), manganese (0.2 ng mL-1), and thallium (0.9 ng mL-1) by flame LEAFS.
