Mid-Infrared Difference Frequency-Generation with Synchronized Fiber Lasers
We present results on high-average power difference frequency generation of pulsed Yb/Er fiber systems to the mid-IR (6.2 W at 3.35 μm), and use focused Gaussian beam theory to validate our experimental results. OCIS codes: (190.4970) Parametric oscillators and amplifiers; (140.3070) Infrared and far-infrared lasers; (140.3510) Lasers, fiber
متن کاملWidely-tunable mid-infrared frequency comb source based on difference frequency generation.
We report on a mid-IR frequency comb source of unprecedented tunability covering the entire 3-10 μm molecular fingerprint region. The system is based on difference frequency generation in a GaSe crystal pumped by a 151 MHz Yb:fiber frequency comb. The process was seeded with Raman-shifted solitons generated in a highly nonlinear suspended-core fiber with the same source. Average powers up to 1....
متن کاملMid-infrared optical frequency combs based on difference frequency generation for molecular spectroscopy.
Mid-infrared femtosecond optical frequency combs were produced by difference frequency generation of the spectral components of a near-infrared comb in a 3-mm-long MgO:PPLN crystal. We observe strong pump depletion and 9.3 dB parametric gain in the 1.5 μm signal, which yields powers above 500 mW (3 μW/mode) in the idler with spectra covering 2.8 μm to 3.5 μm. Potential for broadband, high-resol...
متن کاملRapid communication Detection of formaldehyde using mid-infrared difference-frequency generation
Real-time detection and measurement of subppm levels of formaldehyde in ambient air using diodepumped 3.5 μm difference-frequency generation (DFG) in periodically poled LiNbO3 (PPLN) is reported. Minimum detectable concentration of 30 ppb was achieved with a compact, portable room-temperature gas sensor configured for formaldehyde (H2CO) detection. This sensitivity, coupled with high selectivit...
متن کاملSurface-emitting THz sources based on difference-frequency generation in mid-infrared quantum cascade lasers
We report a surface-emitting THz source based on intracavity difference-frequency generation in dual-wavelength midinfrared quantum cascade lasers with integrated giant second-order nonlinear susceptibility. The THz light is coupled out of the waveguide by a second-order grating etched into the laser ridges. In contrast to sources where the differencefrequency radiation is emitted from the face...
