A practically tunable multiwavelength Raman fiber laser based on few-mode fiber Bragg gratings with dynamic range of more than 15 nm is investigated. We achieved a high extinction ratio of more than 45 dB.
We demonstrate a muW-level broadly tunable THz source based on parametric down-conversion in orientation-patterned GaAs pumped by femtosecond pulses from a Tm-doped fiber laser. Generated THz powers should be scalable to mW-levels with this approach.
We report a tunable laser source emitting in the visible (530 nm, 630 nm) and the near infrared (775 nm, 1060 nm, and 1550 nm) regions by frequency summation of a dual wavelength Er/Yb co-doped fiber laser.
We report a bandwidth-enhanced multi-wavelength source from a stimulated Brillouin scattering assisted erbium-doped fiber laser using four-wave-mixing in a 35-cm highly nonlinear bismuth oxide fiber. Tuning of output wavelengths and wavelength spacing have been demonstrated.
We describe a 1080-nm diode master oscillator utilizing a fiber Fabry-Perot tunable filter with subsequent fiber amplification to 9 W output power. 25 MHz linewidth and 5 THz tuning in less than 1 ms were achieved.
Near infrared emission with a bandwidth more than 450 nm which should be useful for ultra broadband optical amplifiers and tunable lasers for optical telecommunication, has been observed from Bi-doped lithium alumino silicate glass.
