053 μm. The absorption spectrum of ammonia was offered to demonstrate the feasibility of the developed optical parametric oscillator program for spectroscopic measurements and fuel detection.
We report with a femtosecond optical parametric oscillator (OPO) for that deep-infrared (deep-IR) based upon the Kerr-lens-manner-locked Ti:sapphire laser given that the pump resource. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO dependant on the nonlinear crystal, CdSiP two , synchronously pumped inner to a MgO:PPLN femtosecond OPO, Now we have produced broadly tunable radiation throughout 5958�?117 nm working with immediate static cavity hold off tuning, that has a most electric power of 64 μW at 6791 nm, restricted by the absorption in mirror substrates and polarization-dependent intracavity losses.

Reports of practical pump laser systems suitable for ultrafast femtosecond OPOs dependant on CdSiP 2 are talked about, as well as the favorable linear and nonlinear optical properties, together with special stage-matching traits of CdSiP two , are presented using The newest Sellmeier equations for the material. The described experimental success symbolize the very best output pulse Electricity and report common ability within the ultrafast picosecond and femtosecond time scales throughout the six–7 μm spectral assortment to this point.
During this work, we existing what is, to our information, the very first measurements on the quantum period diffusion noise of a cw OPO. Read through a lot 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 continually tuned from one.261 by means of two.532 μm by varying the pump wavelength. Two key improvements had been reached, including the link of your sign and idler tuning ranges and also the large output pulse Electricity in the sign and idler tuning ... [Display total abstract] ranges. The 1st advancement was achieved by discovering two particular sets of phase-matching angles. The 2nd advancement was understood by utilizing 5 sets of resonator mirrors for oscillating either signal or idler.
The era of tunable pico- and femtosecond gentle pulses with parametric frequency conversion procedures has captivated greater notice recently1. New crystal products, as BBO, LBO, and check here KTP, with superior nonlinearity and high damage threshold are now available, and pump lasers of enhanced stability allow the dependable operation of optical parametric oscillators. Parametric gadgets pumped ... [Present total abstract] both by cw modelocked lasers or by solitary intensive ultrashort pulses are already designed. With this contribution parametric programs are mentioned that are pumped by rigorous pulse trains of some microseconds length and repetition rates up to 50Hz.
A way is developed to resolve the procedure of shortened equations describing parametric era in a very a single-frequency OPO cavity less than nanosecond pulsed pumping. The frequency conversion coefficient for ZnGeP2, AgGaSe 2, and HgGa2S4 crystals along with the exceptional reflection coefficient of your output mirror are believed vs . the pump Strength density Wp at various values in the OPO nonstationarity .
The precise warmth and thermal conductivity of HgGa2S4 are measured. It really is concluded the put together Houses of HgGa2S4 crystals can provide for them a leading situation Among the many components used in nonlinear-optical equipment for mid-IR-frequency conversion.
The technology of rising mercury thiogallate crystals (HgGa2S4) is enhanced and substantial-high quality bulk samples are manufactured. The essential optical and thermal Homes of such crystals are analyzed. The transmission spectra of mercury thiogallate are measured and its nonlinear characteristics like the quadratic susceptibility, tuning curves, plus the optical-harm resistance also are identified.
Interference is observed concerning the spontaneous parametric radiation from two nonlinear crystals divided by a macroscopic
The observed file -to- 2 file frequency beats, originating directly from the OPO, can be used for self-referencing and stage locking of your pump laser comb without having for supercontinuum technology. With a median output energy of �?thirty mW , this set up may be helpful for various spectroscopic apps from the mid-IR.
Current mid-IR NLO crystals is often divided into 4 classes, i.e., classical binary and ternary steel pnictides and chalcogenides, quaternary steel chalcogenides, binary and ternary metallic halides, and various-bond-variety hybrid compounds that contain a minimum of two sorts of obviously distinct chemical bonds from the crystal buildings. Metal pnictides and chalcogenides have received Considerably notice on growing huge crystals. Diverse-bond-form hybrid is a completely new family members of mid-IR NLO components, and several of these ended up present in the final 10 years. In steel halide process, both development in growing big crystals and finding new types are already manufactured.
Tunable mid-IR radiation is attained throughout 2nd harmonic era of tunable CO2-laser radiation employing a CdGeAs2 crystal. Its angular tuning characteristics for the CO2- laser wavelength, angular acceptance angle and spectral acceptance are measured.
