and operating ailments for the practical structure of higher electrical power femtosecond optical parametric oscillators with excitation
Output idler energies to the microjoule degree are received with utmost conversion performance of 11% for your amplifier stage, that is a lot more than two occasions much better than the results acquired by having an analogous sample in the extensively unfold product AgGaS 2 .
This technique permits the Procedure of broadly tunable optical parametric oscillators2 (OPO) and subsequent variation frequency generators3 producing tunable pulses of large peak energy. The higher Strength from the pump pulse trains has selected Added benefits to the operation of the synchronously pumped OPO, e.g., comfortable balance specifications, along with the opportunity to operate with substantial cavity losses (e.g. metallic mirrors) permitting significant tuning ranges with only one list of mirrors and significant output-coupling aspects for pulse shortening.
Scientific tests of viable pump laser technologies suitable for ultrafast femtosecond OPOs determined by CdSiP 2 are talked over, and the favorable linear and nonlinear optical Homes, together with special stage-matching characteristics of CdSiP two , are presented applying The newest Sellmeier equations for the material. The described experimental success represent the highest output pulse Power and file regular electrical power from the ultrafast picosecond and femtosecond time scales over the six–seven μm spectral selection up to now.
We report new experimental results about the stage-matching Qualities of yellow shade HgGa2S4 crystals for harmonic generation of an Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers during the 0.944-10.5910 μm variety. In addition, we present new Sellmeier equations that supply a good copy in the existing experimental benefits along with the published facts details for 2nd-harmonic generation of CO2 laser radiation at nine.
This double rectangle is quantitatively described and is also in keeping with previous effects documented while in the literature. Also, numerical simulations are accustomed to validate our analytical design on a doubly resonant OPO and exhibit regular success. The numerical simulations also demonstrate that an optimal top rated-hat temporal profile could present performances very close to those accomplished With all the exceptional double rectangle.
The era of tunable pico- and femtosecond light pulses with parametric frequency conversion procedures has attracted improved notice recently1. New crystal supplies, as BBO, LBO, and KTP, with top-quality nonlinearity and higher damage threshold are now accessible, and pump lasers of improved security enable the trusted operation of optical parametric oscillators. Parametric equipment pumped ... [Exhibit complete abstract] both by cw modelocked lasers or by single intensive ultrashort pulses happen to be made. Within this contribution parametric programs are discussed which happen more info to be pumped by extreme pulse trains of some microseconds duration and repetition costs around 50Hz.

3% rms more than twelve h in excellent beam high quality. The near-IR signal pulses with the OPO have a Gaussian pulse period of �?19 ps , measured at 1284 nm. We now have investigated the temperature tuning qualities on the OPO and as opposed the data With all the theoretical calculations working with the most recent Sellmeier equations and thermo-optic coefficients with the crystal. To the very best of our know-how, This is actually the very first picosecond OPO depending on CSP functioning at MHz repetition premiums.
