053 μm. The absorption spectrum of ammonia was presented to demonstrate the feasibility of your created optical parametric oscillator program for spectroscopic measurements and fuel detection.
We report on the femtosecond optical parametric oscillator (OPO) with the deep-infrared (deep-IR) depending on the Kerr-lens-method-locked Ti:sapphire laser as the pump resource. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO according to the nonlinear crystal, CdSiP 2 , synchronously pumped interior to your MgO:PPLN femtosecond OPO, We've got generated broadly tunable radiation throughout 5958�?117 nm utilizing swift static cavity delay tuning, with a most electric power of 64 μW at 6791 nm, confined through the absorption in mirror substrates in addition to polarization-dependent intracavity losses.

Scientific tests of practical pump laser technologies well suited for ultrafast femtosecond OPOs according to CdSiP 2 are talked about, along with the favorable linear and nonlinear optical properties, and also one of a kind phase-matching traits of CdSiP two , are introduced utilizing The latest Sellmeier equations for the material. The explained experimental effects stand for the highest output pulse energy and record regular electricity while in the ultrafast picosecond and femtosecond time scales across the six–seven μm spectral selection up to now.
We report new experimental outcomes to the section-matching properties of yellow colour HgGa2S4 crystals for harmonic generation of an Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers in the 0.944-10.5910 μm selection. Furthermore, we present new Sellmeier equations that provide a superior replica with the existing experimental benefits and also the printed facts points for next-harmonic era of CO2 laser radiation at 9.
The measured core level binding energies are as opposed with People of HgS, GaS, AgGaS2 and SrGa2S4 compounds. The valence band spectrum proves being independent on the technological circumstances of crystal progress. In contrast to the valence band spectrum, the distribution of electron states while in the bandgap of more info HgGa2S4 crystals is discovered being strongly dependent on the technological situations of crystal development as shown by the photoluminescence Assessment.
The technology of tunable pico- and femtosecond mild pulses with parametric frequency conversion processes has captivated improved awareness recently1. New crystal supplies, as BBO, LBO, and KTP, with excellent nonlinearity and high destruction threshold are now offered, and pump lasers of improved steadiness enable the trusted Procedure of optical parametric oscillators. Parametric gadgets pumped ... [Clearly show entire summary] either by cw modelocked lasers or by one intensive ultrashort pulses have been made. During this contribution parametric programs are talked over which might be pumped by powerful pulse trains of some microseconds period and repetition rates nearly 50Hz.
We existing a numerical study for the design of effective MgO:PPLN based mostly pulsed nanosecond optical parametric oscillator (OPO), with input pump pulses of prime-hat transverse depth profile, along with a double-pass pump cavity configuration. Especially, we look into the impact of area form on the conversion effectiveness. We regarded as two different types of domain structures: "great vertical-wall" and "wedge-formed" domains and our numerical benefits clearly show that at better pump pulse energies, the conversion effectiveness saturates, and the saturated efficiency is nearly unbiased of the domain designs.
Bigger-get nonlinear procedures in substitute elements are also regarded as and a dialogue on substance suitability for down-conversion of in the vicinity of-IR lasers to the mid-IR to fulfill several software demands is also offered.
stabilize and tune the OPO, from which the sound etalon gave a much better functionality. Temperature oscillations while in the PPLN crystal
Normalization from the absorption alerts in the PAD is performed based on the absorption alerts from the gas-stuffed
We report a broadband optical parametric oscillator (OPO) pumped by a Yb-doped fiber laser system. By using a three hundred μm long magnesium-doped periodically poled LiNbO three crystal given that the parametric achieve medium and configuring the OPO being a chirped-pulse oscillator, we obtained mid-infrared emission getting an instantaneous bandwidth masking 3084�?466 nm. This outcome signifies, to the most beneficial of our expertise, the widest instantaneous bandwidth attained from the Yb-fiber-laser-pumped singly resonant OPO, demonstrating the huge prospective of chirped-pulse oscillation in scaling the instantaneous bandwidth of extremely-quickly OPOs.
A simple quantum product agrees properly Together with the experimental final results and makes it probable to interpret the influence regarding
Variation frequency mixing of strongly focused Gaussian beams in periodically poled LiNbO3 was investigated. The beams were focused inside the crystal with no damage. Mixing of cw and pulsed laser units was utilized to minimize the thermal lensing outcomes within this crystal. A low-energy cw 1.064‐μm Nd:YAG laser beam was applied given that the pump, Whilst the signal beam arrived from the picosecond optical .
