Optical parametric oscillator pumped at ~one µm with intracavity mid-IR difference-frequency generation in OPGaAs
We report over a femtosecond optical parametric oscillator (OPO) with the deep-infrared (deep-IR) according to the Kerr-lens-manner-locked Ti:sapphire laser since the pump supply. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO based upon the nonlinear crystal, CdSiP two , synchronously pumped internal to some MgO:PPLN femtosecond OPO, We now have generated broadly tunable radiation across 5958�?117 nm using immediate static cavity delay tuning, with a utmost power of sixty four μW at 6791 nm, minimal because of the absorption in mirror substrates together with polarization-dependent intracavity losses.

In the two the circumstances obtained unit cell parameters are exact, which displays the precision of present approach. The electronic band buildings show the semiconducting conduct in equally the conditions. The density of states plot are also studied and reviewed.
In this perform, we current what is, to our awareness, the very first measurements on the quantum stage diffusion sound of a cw OPO. Read through far more
We report the implementation of the KTP optical parametric oscillator pumped by a pulsed Ti:sapphire laser. Such as signal and idler, it could be continually tuned from 1.261 via 2.532 μm by various the pump wavelength. Two main enhancements had been accomplished, such as the relationship of your sign and idler tuning ranges along with the significant output pulse Electricity with the sign and idler tuning ... [Show entire abstract] ranges. The 1st improvement was attained by discovering two unique sets of section-matching angles. The next enhancement was realized by making use of five sets of resonator mirrors for oscillating both signal or idler.
When applying an institutional account for this Web-site we don’t keep track of any individual, overall performance, functional or 1st or third get together similar facts.
A method is produced to resolve the technique of shortened equations describing parametric technology inside of a a single-frequency OPO cavity less than nanosecond pulsed pumping. The frequency conversion coefficient for ZnGeP2, AgGaSe two, and HgGa2S4 crystals and also the ideal reflection coefficient of your output mirror are estimated versus the pump Electrical power density Wp at various values on the OPO nonstationarity .
Higher-buy nonlinear procedures in different elements will also be regarded plus a discussion on product suitability for down-conversion of in close proximity to-IR lasers to the mid-IR to meet various application needs is likewise presented.

... The very first details about the refractive index of orange HGS printed by Levine et al. [35] involved only handful of wavelengths within the seen and in the vicinity of-IR just as an illustration from the feasibility of the crystal for birefringent section-matching. The refractive indices for your orange period were HgGa2S4 Crystal being measured and tabulated among 0.
We report a broadband optical parametric oscillator (OPO) pumped by a Yb-doped fiber laser method. By making use of a 300 μm prolonged magnesium-doped periodically poled LiNbO three crystal because the parametric get medium and configuring the OPO as being a chirped-pulse oscillator, we acquired mid-infrared emission owning an instantaneous bandwidth covering 3084�?466 nm. This end result represents, to the most effective of our know-how, the widest instantaneous bandwidth attained from the Yb-fiber-laser-pumped singly resonant OPO, demonstrating the enormous probable of chirped-pulse oscillation in scaling the instantaneous bandwidth of extremely-rapid OPOs.
With this paper we theoretically investigate one of the most effective pump temporal condition for pulsed operation of optical parametric oscillators (OPOs). The theoretical Assessment is made up of solving the best Manage challenge using the charge equation formalism. The OPO exceptional buildup behavior is derived for virtually any OPO configuration, and we demonstrate which the optimal pump pulse shape is often a double rectangle. The first rectangle is optimized for your buildup approach, even though the 2nd a person is optimized for the regular state, and the two rely in different ways over the OPO mirror reflectivities plus the available pump Electrical power and utmost peak electric power.
Tunable mid-IR radiation is attained through second harmonic technology of tunable CO2-laser radiation using a CdGeAs2 crystal. Its angular tuning characteristics within the CO2- laser wavelength, angular acceptance angle and spectral acceptance are measured.
