Available in PDF, EPUB and Kindle. Book excerpt: We have constructed and fielded a multi-wavelength injection seeded mid-IR OPO source for DIAL. This OPO system was built for ground based remote sensing measurements of species with both broad (300 cm−1) and narrow absorption bandwidths (0.07 cm−1 FWHM). The OPO utilizes a single frequency tunable diode laser for the injection seeded signal wavelength in the region from 6400 to 6700 cm−1 and an angle phase-matched 5 cm LiNbO3 crystal to provide large tuning excursions on a slow time scale. The pump was a diode pumped Nd:YAG MOPA (9398 cm−1) running at 180 Hz. This pump source was repeatedly injection seeded with a different wavelength on each of film sequential shots forming a set of three pulses having wavelength separations on the order of 0.4 cm−1 at a three color set repetition rate of 60 Hz. This combination of OPO signal and pump source produced a set of three time staggered idler wavelengths separated by 0.4 cm−1 with the center wavelength tunable from 2700 to 3000 cm−1. This OPO system was used in field test experiments to detect the release of chemicals from a standoff distance of 3.3 Km. We present key OPO design criteria, performance data, and numerical simulations that agree with our observations of pump induced spectral impurities in the OPO output.

Book excerpt: Optical parametric oscillators (OPO) and systems are provided. The OPO has a non-linear optical material located between two optical elements where the product of the reflection coefficients of the optical elements are higher at the output wavelength than at either the pump or idler wavelength. The OPO output may be amplified using an additional optical parametric amplifier (OPA) stage.

This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis reports experimental indirect spectral transfer of shaped pulses from the near to mid-infrared via the use of an optical parametric oscillator. It was shown that good spectral fidelity of transfer can be achieved by making suitable adjustments to the OPO. The issues affecting the transfer process are discussed and experimental results are compared with existing theory. The shaping of the nearinfrared pulses was performed using a zero dispersion pulse shaper and a computer controlled spatial light modulator. A suitable search algorithm was written and, with the use of appropriate computer hardware, allowed a closed-feedback loop to be implemented. The computer controlled hardware was demonstrated to be able to autonomously optimise simple experiments in the mid-infrared and optimise the threshold of an optical parametric oscillator.

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract : We demonstrate a high-efficiency mid-infrared picosecond optical parametric oscillator (OPO) based on MgO doped periodically poled lithium niobate (MgO:PPLN) with a laser diode array (LDA) pumped Innoslab amplifier as the pumping source. Under a 16 W synchronously pumping power, 4.5 W of idler light at 2896 nm is obtained. A tuning range of idler light from 2688 nm to 3016 nm is achieved, within which the highest optical-optical conversion efficiency from pump power to OPO output is 35.1%. Moreover, a signal light of ∼500 mW from 1644 to 1700 nm with a repetition rate of 233.8 MHz is generated.
