“…Such tunable fiber sources based on parametric generation in PM PCFs may be competitive both with conventional tunable lasers such as Ti-Sapphire laser and with alternative tunable fiber laser systems in visible, e.g. based on frequency doubling [35,36].…”

CW parametric generation in polarization maintaining PCF pumped by Yb-doped fiber laser

2012

Phase matching curves for parametric generation in four wave mixing (FWM) processes of different types are studied experimentally and numerically for a polarization maintaining photonic crystal fiber (PCF) pumped by a tunable continuous wave (CW) ytterbium doped fiber laser near 1 μm. Parametric frequency shifts up to 100 THz for scalar and pump-divided vector FWM processes are observed providing generation of idler wave with wavelengths as short as 765 and 758 nm for the two processes respectively. Explicit analytical solutions for scalar and polarization phase matching in vicinity of the zero dispersion wavelength have been also deduced. They are based on phase mismatch Taylor series expansion taking into account the polarization contribution. A good quantitative agreement between experimental and calculated frequency shifts is demonstrated.

“…The low intensity enhancement coefficient is shown to be reasoned by the spectral broadening effects, which lead to significant increase of the highly-reflective FBG transmission (from 1% to 20% with increasing power), as shown in Fig. 3(b) [8], used as narrow-band cavity reflector. To reduce this effect we have applied large-mode area active fibers providing lower intensity at the same power thus decreasing nonlinear effects.…”

“…At the long-wavelength part of the Yb 3+ gain curve, the intra-cavity scheme leads to~3 times increase of the second-harmonic (SH) output power compared to the single-pass one, as shown in Fig. 3(a) [8]. At that, factor~2 is due to double-pass conversion and factor~1.5 is due to intensity enhancement inside the cavity compared to the same YDFL power with output coupler at the same pumping (~20 W LD at 976 nm).…”

A review of the main physical processes important for frequency doubling of fiber lasers and the results of development by the Novosibirsk group of the fiber lasers operating from blue-green to yellow-red spectral ranges with a potential of the broad continuous tuning are presented. These lasers with~100 mW power are treated to be attractive light sources for applications in medicine, especially in confocal microscopy and flow cytometry.

“…RFLs are well-known robust fiber laser sources providing almost any wavelength in the near-IR range (1.1-1.7 mkm) [1]. In addition, RFLs can easily generate multiple wavelengths simultaneously [2], their output radiation can be tuned over a wide frequency range in an all-fiber configuration by using tunable FBGs [3,4] or by using tunable pump source [5]. All these features make RFLs useful in various fields including supercontinuum generation [6] and medical applications [7][8].…”

Extreme value statistics in Raman fiber lasers

2012

We present the numerical study of the statistical properties of the partially coherent quasi-CW high-Q cavity Raman fiber laser. The statistical properties are different for the radiation generated at the spectrum center or spectral wings. It is found that rare extreme events are generated at the far spectral wings at one pass only. The mechanism of the extreme events generation is a turbulent-like four-wave mixing of numerous longitudinal generation modes. The similar mechanism of extreme waves appearance during the laser generation could be important in other types of fiber lasers.
