چکیده
A multi-wavelength mid-IR laser consisting of 3.05 μm, 4.25 and 5.47 μm BaGa 4 Se 7 (BGSe)optical parametric oscillators (OPOs) switched by DKDP electro-optic switches with one 10 Hz/7.6 ns pumping wave is demonstrated. Maximum energies at are 1.35 mJ, 1.03 0.56 respectively, corresponding to optical-to-optical conversion efficiencies 9.4%, 7.6%, 4.2%. To the best our knowledge, this study first generation three wavelength lasers using switches. Furthermore, provides a viable solution for high-energy or high-power, compact, even portable device that employs single wave.

Fiber-laser-pumped, high-energy, mid-IR, picosecond optical parametric oscillator with a high-harmonic cavity.
We demonstrate the generation of high-energy, mid-IR, picosecond pulses in a high-harmonic-cavity optical parametric oscillator (OPO) that has a relatively compact cavity with a length that is a small fraction of that required to match the pump repetition rate. The OPO, based on an MgO-doped periodically poled LiNbO3 crystal, is pumped by a fiber master-oscillator-power-amplifier system employi...
متن کاملWavelength-dependent collagen fragmentation during mid-IR laser ablation.
Mid-infrared free-electron lasers have proven adept in surgical applications. When tuned to wavelengths between 6 and 7 microm, such lasers remove defined volumes of soft tissue with very little collateral damage. Previous attempts to explain the wavelength-dependence of collateral damage have invoked a wavelength-dependent loss of protein structural integrity. However, the molecular nature of ...
متن کاملOptical parametric oscillators for precision IR spectroscopy and metrology
This thesis presents a continuous-wave optical parametric oscillator (cw OPO), specially developed for high-resolution Doppler-free molecular spectroscopy and metrology. The basic objective was to solve the long-standing problem of controlled access to any desired wavelength in the wide emission range of OPOs, including the ability to precisely tune the output frequency over the molecular and a...

متن کاملMid-IR frequency comb source spanning 4.4-5.4 μm based on subharmonic GaAs optical parametric oscillator.
Broadband mid-IR output suitable for producing 1000-nm-wide frequency combs centered at 4.9 μm was achieved in a degenerate subharmonic optical parametric oscillator (OPO) based on 500-μm-long Brewster-angled orientation-patterned GaAs crystal. The OPO was synchronously pumped at 182 MHz repetition rate by 100 fs pulses from a Cr²⁺:ZnSe laser with the central wavelength of 2.45 μm and the avera...
