Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR difference-frequency technology in OPGaAs
We report on the femtosecond optical parametric oscillator (OPO) to the deep-infrared (deep-IR) according to the Kerr-lens-manner-locked Ti:sapphire laser as being the pump source. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO dependant on the nonlinear crystal, CdSiP two , synchronously pumped interior to a MgO:PPLN femtosecond OPO, We have now generated broadly tunable radiation throughout 5958�?117 nm using swift static cavity delay tuning, using a maximum electric power of 64 μW at 6791 nm, constrained by the absorption in mirror substrates in addition to polarization-dependent intracavity losses.
Aside from the compactness and benign operating characteristics, it absolutely was the enormous overall flexibility in structure and output traits that led for the success of sound-condition lasers throughout the last forty years.
A straightforward strategy for minimizing the loss that is due to depolarization ensuing from thermally induced strain birefringence in reliable-state lasers is described. The technique makes use of a single intracavity quarter-wave plate with its quick or gradual axis aligned parallel to the preferred aircraft of polarization, described by an intracavity polarizer.
On this function, we present what on earth is, to our awareness, the primary measurements of your quantum phase diffusion noise of the cw OPO. Read a lot more
The large conversion efficiency and wide range of radiation wavelength tuning will allow to hope this materials could contend with AgGaS2, AgGaSe2, ZnGeP2 and GaSe crystals in spite of the substantial difficulty of huge dimension crystals advancement course of action.
The technology of tunable pico- and femtosecond light-weight pulses with parametric frequency conversion procedures has attracted elevated consideration recently1. New crystal resources, as BBO, LBO, and KTP, with superior nonlinearity and high problems threshold are actually accessible, and pump lasers of enhanced balance enable the trusted Procedure of optical parametric oscillators. Parametric products pumped ... [Present full abstract] both by cw modelocked lasers or by one powerful ultrashort pulses have already been developed. In this particular contribution parametric programs are talked about that are pumped by powerful pulse trains of some microseconds duration and repetition costs up to 50Hz.
A method is developed to resolve the process of shortened equations describing parametric era inside a one-frequency OPO cavity less than nanosecond pulsed pumping. The frequency conversion coefficient for ZnGeP2, AgGaSe 2, and HgGa2S4 crystals as well as ideal reflection coefficient from the output mirror are believed versus the pump Vitality density Wp at various values of your OPO nonstationarity .
Larger-purchase nonlinear processes in choice materials will also be thought of along with a dialogue on substance suitability for down-conversion of in the vicinity of-IR lasers to the mid-IR to satisfy a variety of software necessities can be introduced.
Evaluation of recent, promising wide-band-gap nonlinear crystals for your mid-IR is provided. We focused on ternary and quaternary chalcogenides and primarily based on their Actual physical and chemical Qualities, which As well as linear and nonlinear optical Qualities, ascertain the performance of crystal utilization in specified laser experiments. The correlation amongst the composition, framework and output parameters plus the developments in adjustments of the primary qualities like band hole, nonlinear susceptibility, laser injury threshold, and so on, are shown.
Uncomplicated method for reducing the depolarization loss ensuing from thermally induced birefringence in strong-state lasers
twelve μm and describe all frequency conversion techniques recognized so far with them together with potential potential programs. Keywords: Ternary and quaternary semiconductors, defect chalcopyrites, reliable solutions, nonlinear optical crystals, mid-infrared
Mid-IR 2nd-purchase NLO crystal is indispensable while in the frequency conversion programs inside the mid-IR region. Compared with DUV and UV/Vis/around-IR NLO crystals, functional mid-IR NLO crystals are reasonably uncommon, and many of these remain on the phase of laboratory exploration. This chapter testimonials the current development within the mid-IR NLO crystals, which mainly contains expanding the classical mid-IR NLO crystals into significant substantial-high-quality ones or into quasi-phase-matching buildings which are ideal for the laser gadgets by various growth solutions and Discovering new potential mid-IR NLO crystals by introducing new style and design and synthesis methods.
Big difference frequency mixing of strongly centered Gaussian beams in periodically poled LiNbO3 was investigated. The beams ended up centered Within the crystal devoid of problems. get more info Mixing of cw and pulsed laser devices was utilized to minimize the thermal lensing effects inside of this crystal. A low-energy cw one.064‐μm Nd:YAG laser beam was applied as being the pump, While the signal beam arrived from the picosecond optical .
