With the advent of new nonlinear components and single-frequency pump resources, there is renewed interest in optical parametric oscillators (OPOs). A single-method diode-laser-pumped monolithic Nd:YAG nonplanar ring laser that's equally amplified and frequency doubled is utilized to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.
Benefits of thermal conductivity measurements are claimed for several of the greater not long ago produced nonlinear optical crystals. New or considerably revised values of thermal conductivity have been received in 6 products. Notable thermal conductivities measured were These for AgGaS2 [0.014 W/(cm K) and 0.

In each the scenarios received device mobile parameters are very same, which shows the precision of current method. The electronic band buildings exhibit the semiconducting habits in both of those the situations. The density of states plot may also be analyzed and reviewed.
We report new experimental results on the period-matching Homes of yellow colour HgGa2S4 crystals for harmonic generation of the Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers within the 0.944-10.5910 μm range. Also, we existing new Sellmeier equations that provide a excellent replica of the present experimental results together with the revealed details details for second-harmonic generation of CO2 laser radiation at nine.
We report the implementation of a KTP optical parametric oscillator pumped by a pulsed Ti:sapphire laser. Together with sign and idler, it could be continually tuned from one.261 via 2.532 μm by different the pump wavelength. Two main enhancements were reached, such as the connection from the signal and idler tuning ranges and also the large output pulse Power in the sign and idler tuning ... [Display entire summary] ranges. The 1st enhancement was accomplished by identifying two distinct sets of section-matching angles. The 2nd advancement was realized by making use of 5 sets of resonator mirrors for oscillating both sign or idler.

This new version has long been current and revised to includeimportant developments, principles and systems that haveemerged Considering that the publication of the very first version.
Modeling and experimental examine on phase matching of 2nd harmonic generation in several colour Hg Ga 2 S 4 crystals are carried out. Utilizing the regarded Sellmeier equations, the dispersion relation with weighting proportionally to small-wavelength boundary in the crystal transparency band is proposed.
The third harmonic of CO2-laser radiation continues to be acquired by passing the laser beam by means of two CdGeAs2 crystals in tandem, with the initial crystal oriented for second-harmonic generation and the next for sum mixing. Employing This method, We have now accomplished an average exterior conversion efficiency of 1.
Interference is observed concerning the spontaneous parametric radiation from two nonlinear crystals separated by a macroscopic
12 μm and explain all frequency conversion strategies understood to this point with them as well as potential probable purposes. Search phrases: Ternary and quaternary semiconductors, defect chalcopyrites, reliable methods, nonlinear optical crystals, mid-infrared
Within this paper we theoretically investigate essentially the most effective pump temporal shape for pulsed Procedure of optical parametric oscillators (OPOs). The theoretical Assessment consists of resolving the ideal Command issue utilizing the charge equation formalism. The OPO optimal buildup behavior is derived for just about any OPO configuration, and we exhibit which the optimum pump pulse condition check here is a double rectangle. The primary rectangle is optimized for that buildup course of action, though the 2nd a single is optimized for that continuous condition, and both equally rely in different ways to the OPO mirror reflectivities along with the obtainable pump Strength and greatest peak power.
three% rms more than twelve h in fantastic beam high quality. The around-IR sign pulses from the OPO have a Gaussian pulse period of �?19 ps , calculated at 1284 nm. We've got investigated the temperature tuning attributes of the OPO and compared the info With all the theoretical calculations making use of the most recent Sellmeier equations and thermo-optic coefficients to the crystal. To the top of our awareness, this is the initial picosecond OPO dependant on CSP operating at MHz repetition prices.
