We demonstrate, for the first time to the best of our knowledge, four wave mixing (FWM) process in a 900 nm wavelength region. A 54 m highly nonlinear photonic crystal fiber (HN-PCF) is used as nonlinear medium, and continuous wave laser diodes at near 975 nm are selected as pump sources. By simultaneously injecting two pump sources into the HN-PCF, FWM is observed with wavelength spacing of 0.4 nm and 2 nm, respectively. Compared with FWM in conventional highly nonlinear fibers, HN-PCF one possesses much higher conversion efficiency. These FWMs introduce an opportunity to extend the wavelength coverage of fiber lasers and amplifiers in 900 nm waveband, and also indicate that HN-PCFs can have great potential for FWM applications towards short wavelength regions.

“…141 As the dispersion zero shifts to shorter wavelengths, the inner core of the photonic crystal fibers decreases and coupling efficiencies generally tend to decrease. An additional problem is also that to maintain phase matching over the extended lengths of fiber used, exacting control of the fiber parameters is vital and places severe limits on feature sizes.…”

Abstract. Fiber-based lasers and master oscillator power fiber amplifier configurations are described. These allow spectral versatility coupled with pulse width and pulse repetition rate selection in compact and efficient packages. This is enhanced through the use of nonlinear optical conversion in fibers and fiber-coupled nonlinear crystals, which can be integrated to provide all-fiber pump sources for diverse application. The advantages and disadvantages of sources based upon supercontinuum generation, stimulated Raman conversion, four-wave mixing, parametric generation and difference frequency generation, allowing spectral coverage from the UV to the mid-infrared, are considered.

“…3). The design of the module was based on a previous iteration for generation of 780 nm light, highlighting the wavelength flexibility of the concept [9]. Inside the module, a 15 mm long 5% MgO-doped congruent lithium niobate crystal, held in a metal housing, was bonded to a thermoelectric cooler (TEC).The crystal had a thickness of 1 mm, a width of 3 mm and a manufacturer quoted effective nonlinear coefficient of > 14 pm/V.…”

Abstract:We report the development of a fiber-integrated picosecond source at 560 nm by second harmonic generation of a Raman fiber laser. A picosecond ytterbium master oscillator power fiber amplifier is used to pulse-pump a Raman amplifier, which is seeded by a continuous wave distributed feedback laser diode operating at 1120 nm. The pulse train generated at 1120 nm is frequency-doubled in a fiber-coupled periodicallypoled lithium niobate crystal module, producing 450 mW of average power at 560 nm with a pulse duration of 150 ps at a repetition rate of 47.5 MHz. The near diffraction-limited (M 2 = 1.02) collimated output beam is ideal for super-resolution microscopy applications.
