With the appearance of new nonlinear elements and solitary-frequency pump resources, There may be renewed fascination in optical parametric oscillators (OPOs). One-method diode-laser-pumped monolithic Nd:YAG nonplanar ring laser that is both of those amplified and frequency doubled is utilized to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.
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 because the pump source. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO determined by the nonlinear crystal, CdSiP two , synchronously pumped inside to the MgO:PPLN femtosecond OPO, We've produced broadly tunable radiation throughout 5958�?117 nm using fast static cavity delay tuning, by using a most ability of sixty four μW at 6791 nm, minimal by the absorption in mirror substrates along with polarization-dependent intracavity losses.
crystals with ultrafast Yb-ion laser pump is proposed. The results type a valuable reference for the selection of components
The concept of chemical transportation reactions (volatilization of a fabric through a low-risky chemical intermediate at a temperature T1 and again-reaction of your mixture in a temperature T2, using the temperature dependence of your chemical equilibrium concerned) is a worthwhile Instrument for increasing solitary crystals of numerous components which can not be effortlessly received in the melt.
Self-referenced octave-vast subharmonic GaP optical parametric oscillator centered at three μm and pumped by an Er-fiber laser
The calculated core degree binding energies are in contrast with All those of HgS, Fuel, AgGaS2 and SrGa2S4 compounds. The valence band spectrum proves to get impartial about the technological disorders of crystal development. In distinction into the valence band spectrum, the distribution of electron states while in the bandgap of HgGa2S4 crystals is discovered being strongly dependent on the technological disorders of crystal advancement as demonstrated through the photoluminescence Assessment.
The temperature dependence of refractive indices of optical materials is characterized On this do the job by what we call their normalized thermo-optic coefficients. They are determined experimentally by means of interferometric measurements of thermal expansion and of modifications in optical thickness at some laser wavelengths as function of temperature. An appropriate vectorial formalism placed on these data permits predicting the thermal evolution in the refractive index all over the practical choice of transparency.
We present a numerical examine for the design of successful MgO:PPLN based pulsed nanosecond optical parametric oscillator (OPO), with input pump pulses of prime-hat transverse intensity profile, plus a double-go pump cavity configuration. In particular, we look into the result of area form around the conversion performance. We considered two different types of area buildings: "fantastic vertical-wall" and "wedge-formed" domains and our numerical final results demonstrate that at bigger pump pulse energies, the conversion efficiency saturates, and also the saturated efficiency is sort of independent with the domain styles.
Vibrational spectra of Li-containing nonlinear crystals as well as their software in THz radiation generation are talked about. Making use of an illustration of LiGaS2, the defect impact on spectroscopic more info traits is proven. Substantial-temperature annealing in a proper environment enables a single to get rid of prolonged and stage defects and to Enhance the transparency. Strength framework and parameters of key issue defects such as anion vacancy (File-Centre) and cation antisite defect GaLi calculated from the first principles concur well Using the experimental outcomes.
This paper assessments the latest developments in crystal growth and singly resonant optical parametric oscillators for the technology of higher one pulse Electricity and regular powers from the mid-IR from 3 to 10 μm.
The system relies on group velocity matching amongst interacting waves Besides birefringent section matching. We will explain broadband SHG qualities when it comes to beam propagation directions, spectral positions of resonance, productive nonlinearities, spatial stroll-offs in between interacting beams, and spectral bandwidths. The outcome will show the spectral bandwidths of the elemental wave allowed for broadband SHG to reach a number of hundreds of nm. The corresponding SH spectral vary spans from 1758.58 to 4737.18 nm from the non-oxide crystals regarded as During this study. This sort of broadband SHG making use of small pulse trains can potentially be placed on frequency up-conversion imaging while in the mid-IR area, in information transmission, and in nonlinear optical signal processing.
Notice: Author names is going to be searched inside the key terms discipline, also, but that may uncover papers where the person is outlined, as opposed to papers they authored.
An easy quantum model agrees very well Along with the experimental final results and can make it attainable to interpret the impact concerning
