Optical parametric oscillator pumped at ~one µm with intracavity mid-IR variation-frequency generation in OPGaAs
We report over a femtosecond optical parametric oscillator (OPO) with the deep-infrared (deep-IR) according to the Kerr-lens-method-locked Ti:sapphire laser since the pump resource. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO dependant on the nonlinear crystal, CdSiP 2 , synchronously pumped inside to the MgO:PPLN femtosecond OPO, We now have generated broadly tunable radiation throughout 5958�?117 nm applying fast static cavity delay tuning, by using a most energy of sixty four μW at 6791 nm, restricted via the absorption in mirror substrates together with polarization-dependent intracavity losses.
This system enables the Procedure of greatly tunable optical parametric oscillators2 (OPO) and subsequent variance frequency generators3 making tunable pulses of higher peak power. The higher energy of your pump pulse trains has specific Rewards for your Procedure of a synchronously pumped OPO, e.g., relaxed steadiness demands, along with the possible to operate with large cavity losses (e.g. metal mirrors) making it possible for big tuning ranges with just one set of mirrors and high output-coupling components for pulse shortening.
An easy procedure for lowering the loss that is because of depolarization resulting from thermally induced pressure birefringence in stable-condition lasers is claimed. The strategy makes use of only one intracavity quarter-wave plate with its rapidly or sluggish axis aligned parallel to the preferred aircraft of polarization, described by an intracavity polarizer.
In this particular do the job, we existing what on earth is, to our information, the main measurements of your quantum period diffusion sounds of the cw OPO. Read through more
We report the implementation of the KTP optical parametric oscillator pumped by a pulsed Ti:sapphire laser. Such as sign and idler, it could be constantly tuned from one.261 via two.532 μm by different the pump wavelength. Two significant enhancements ended up attained, including the connection in the signal and idler tuning ranges plus the large output pulse Electricity from the sign and idler tuning ... [Exhibit whole summary] ranges. The primary advancement was accomplished by discovering two specific sets of section-matching angles. The next advancement was realized by making use of five sets of resonator mirrors for oscillating both sign or idler.
The temperature dependence of refractive indices of optical elements is characterized During this do the job by what we get in touch with their normalized thermo-optic coefficients. These are identified experimentally via interferometric measurements of thermal enlargement and of improvements in optical thickness at some laser wavelengths as operate of temperature. A suitable vectorial website formalism placed on these data lets predicting the thermal evolution from the refractive index everywhere in the helpful range of transparency.
air gap and enthusiastic in series by a common pump beam. The period of your interference relies on the period shifts at three frequencies.
Modeling and experimental examine on phase matching of next harmonic generation in numerous color Hg Ga two S four crystals are carried out. Utilizing the recognised Sellmeier equations, the dispersion relation with weighting proportionally to limited-wavelength boundary from the crystal transparency band is proposed.
stabilize and tune the OPO, from which the stable etalon gave a far better performance. Temperature oscillations in the PPLN crystal
Uncomplicated technique for lessening the depolarization loss resulting from thermally induced birefringence in strong-condition lasers
twelve μm and explain all frequency conversion schemes understood to this point with them along with foreseeable future possible purposes. Keywords and phrases: Ternary and quaternary semiconductors, defect chalcopyrites, strong remedies, nonlinear optical crystals, mid-infrared
The selected nonlinear crystals exhibit greater nonlinear conversion efficiency compared to AgGaS 2 , with BaGa two GeS 6 Also supplying a narrower angular spectrum of spontaneous parametric down conversion, useful in interferometric schemes. Our results build a pathway for integrating Innovative crystal systems into mid-infrared metrology and imaging techniques, location the phase for future developments in nonlinear interferometry and spectroscopy.
Diode-pumped optical parametric oscillation has actually been shown for The very first time to our information in just one Nd:MgO:LiNbO3 nonlinear crystal. The crystal is pumped by a semiconductor diode laser array at 812 nm. The Nd³�?ions absorb the 812-nm radiation to deliver 1084-nm laser oscillation.
