With the arrival of recent nonlinear resources and one-frequency pump sources, There's renewed curiosity in optical parametric oscillators (OPOs). An individual-method diode-laser-pumped monolithic Nd:YAG nonplanar ring laser that is definitely both of those amplified and frequency doubled is utilized to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.
We report with a femtosecond optical parametric oscillator (OPO) with the deep-infrared (deep-IR) depending on the Kerr-lens-method-locked Ti:sapphire laser as the pump source. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO depending on the nonlinear crystal, CdSiP two , synchronously pumped inside into a MgO:PPLN femtosecond OPO, We've created broadly tunable radiation across 5958�?117 nm using speedy static cavity hold off tuning, that has a maximum power of sixty four μW at 6791 nm, limited via the absorption in mirror substrates and polarization-dependent intracavity losses.
This technique makes it possible for the operation of commonly tunable optical parametric oscillators2 (OPO) and subsequent big difference frequency generators3 developing tunable pulses of substantial peak energy. The upper Power with the pump pulse trains has particular Positive aspects to the operation of a synchronously pumped OPO, e.g., calm security prerequisites, along with the possible to operate with large cavity losses (e.g. steel mirrors) permitting significant tuning ranges with just one list of mirrors and substantial output-coupling factors for pulse shortening.
An easy strategy for reducing the decline that is because of depolarization resulting from thermally induced anxiety birefringence in sound-condition lasers is documented. The procedure works by using an individual intracavity quarter-wave plate with its quickly or slow axis aligned parallel to the popular aircraft of polarization, defined by an intracavity polarizer.

We report the implementation of the KTP optical parametric oscillator pumped by a pulsed Ti:sapphire laser. Such as signal and idler, it may be constantly tuned from one.261 by 2.532 μm by various the pump wavelength. Two big improvements ended up achieved, including the link in the signal and idler tuning ranges plus the high output pulse Vitality from the sign and idler tuning ... [Show complete abstract] ranges. The initial enhancement was realized by identifying two particular sets of phase-matching angles. The second advancement was understood by using five sets of resonator mirrors for oscillating either sign or idler.

A pulsed TEA CO2 laser was utilized to research the effect of pump radiation parameters (method structure, wavelength, and pulse period), concentrating situations, absorption coefficient, and temperature to the efficiency of conversion into the next harmonic and on angular dependences of phase matching in ZnGeP2 crystals. Excellent arrangement betweeen experimental and theoretical final results is noticed. Browse far more
3% rms in excess of twelve h in superior beam good quality. The near-IR signal pulses within the OPO Have a very Gaussian pulse period of �?19 ps , measured at 1284 nm. We have investigated the temperature tuning attributes with the OPO and compared the info With all the theoretical calculations employing The latest Sellmeier here equations and thermo-optic coefficients for that crystal. To the top of our information, This can be the 1st picosecond OPO based on CSP operating at MHz repetition costs.
