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 کاملMid-IR multiwavelength difference frequency generation based on fiber lasers.
A mid-IR multiwavelength difference frequency generation (DFG) laser source with fiber laser fundamental lights is demonstrated by using the dispersion property of PPLN to broaden the quasi-phase-matching (QPM) acceptance bandwidth (BW). Our results show that the QPM BW for the pump YDFL is much larger than that for the signal EDFL. Using a multiwavelength YDFL and a single-wavelength EDFL as t...
متن کاملMid-Infrared Pulsed Laser Lithotripsy with a Tunable Laser Using Difference-Frequency Generation
A novel technique of lithotripsy was investigated with a mid-infrared tunable pulsed laser using difference-frequency generation (DFG). Human gallstone samples obtained from 24 patients were analyzed with their infrared absorption spectra. It was found that the principal components of the gallstones were different for the different patients and that the gallstone samples used in this research c...
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...
متن کاملBROADBAND MID-INFRARED SOLID-STATE LASERS Broadband Mid-Infrared Lasers
A survey of broadband Co2+and Cr2+-based lasers is presented. These mid-IR sources, operating in the very interesting “molecular fingerprint” region between ∼1.6 and 3.5μm offer the broadest bandwidth from all solid-state vibronic lasers. The emphasize is made on Cr2+-doped lasers, which have not only the widest and the highest gain, but also operate at room-temperature and produce the shortest...
