We report on our research into fluoride fiber-based 3 µm class laser sources. Using holmium as the gain medium, record-high peak power levels are achieved in mode-locked laser systems that emit ultrashort pulses in the water vapor transmission window around 2.9 µm. Highly nonlinear and dispersion-engineered hybrid chalcogenide-polymer microwires are utilized to extend the frequency range of those...
We demonstrate the generation of a flat supercontinuum (SC) at 1550 nm using photonic crystal fiber (PCF) of normal dispersion when injected by a fiber laser that is passively mode locked by single-wall carbon-nanotube-based saturable absorber (SWNT-SA). The self-started mode-locked laser with a threshold power of 52 mW together with the PCF can generate a SC covering 223 nm over the entire C+L band...
In this paper we describe our experiments with mode-locked fiber lasers. Amplified output pulses are used for supercontinuum (SC) generation in non-zero dispersion shifted fiber (NZ DSF). We show that wide output supercontinuum could be generated in standard telecommunication fiber using laser that is passively mode-locked by nonlinear polarization rotation.
By using a recently developed nonlinear fiber, we achieve octave-spanning spectrum directly from a diode-pumped passively mode-locked 250-fs Er:Yb:glass laser without any amplification stage. Applications for CEO phase stabilization and optical clocking are discussed.
