053 μm. The absorption spectrum of ammonia was offered to display the feasibility of the developed optical parametric oscillator procedure for spectroscopic measurements and fuel detection.
We report with a femtosecond optical parametric oscillator (OPO) with the deep-infrared (deep-IR) according to the Kerr-lens-manner-locked Ti:sapphire laser as the pump resource. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO based upon the nonlinear crystal, CdSiP two , synchronously pumped internal into a MgO:PPLN femtosecond OPO, We've generated broadly tunable radiation throughout 5958�?117 nm using quick static cavity delay tuning, that has a most electrical power of sixty four μW at 6791 nm, minimal from the absorption in mirror substrates in addition to polarization-dependent intracavity losses.

In both of those the scenarios attained unit mobile parameters are same, which displays the precision of existing method. The electronic band structures display the semiconducting behavior in both the conditions. The density of states plot may also be examined and talked over.
OPO were improved by optimizing pump beam waist and OPO cavity length. Both of those air-spaced and sound etalons were being tested to frequency
brought on oscillations inside the idler wavelength of below 200MHz over 300s; the quick-expression stability was lower than 3MHz
Optical Houses of orange phased HgGa2S4 crystal is investigated. Technology of tunable middle infrared radiation by second harmonic of tunable CO2 laser radiation has become shown. 2nd harmonic conversion effectiveness with respect to other infrared crystal has also been talked about.
We present a numerical review for the design of successful MgO:PPLN based pulsed nanosecond optical parametric oscillator (OPO), with enter pump pulses of best-hat transverse depth profile, in addition to a double-pass pump cavity configuration. In particular, we investigate the outcome of domain form to the conversion performance. We deemed two varieties of domain structures: "great vertical-wall" and "wedge-formed" domains and our numerical success present that at better pump pulse energies, the conversion performance saturates, plus the saturated efficiency is sort of unbiased of your domain shapes.

Basic approach for cutting down the depolarization loss resulting from thermally induced birefringence in good-condition lasers
We more info report a broadband optical parametric oscillator (OPO) pumped by a Yb-doped fiber laser procedure. By using a three hundred μm lengthy magnesium-doped periodically poled LiNbO three crystal as being the parametric gain medium and configuring the OPO to be a chirped-pulse oscillator, we obtained mid-infrared emission obtaining an instantaneous bandwidth masking 3084�?466 nm. This final result signifies, to the ideal of our expertise, the widest instantaneous bandwidth acquired from the Yb-fiber-laser-pumped singly resonant OPO, demonstrating the huge likely of chirped-pulse oscillation in scaling the instantaneous bandwidth of ultra-rapidly OPOs.
With this paper we theoretically examine essentially the most effective pump temporal shape for pulsed operation of optical parametric oscillators (OPOs). The theoretical analysis consists of solving the best Command issue utilizing the price equation formalism. The OPO ideal buildup behavior is derived for just about any OPO configuration, and we present that the optimal pump pulse condition is often a double rectangle. The very first rectangle is optimized for the buildup approach, whilst the 2nd a person is optimized to the steady condition, and equally depend in different ways within the OPO mirror reflectivities plus the accessible pump Vitality and greatest peak power.
