چکیده

A diode-pumped alkali laser (DPAL) provides the significant promise for high-powered performances. In this paper, a mathematical model is introduced for examination of the kinetic processes of a diode-pumped cesium vapor hollow-core photonic-crystal fiber (HC-PCF) laser, in which the cesium vapor is filled in the center hole of a photonic-bandgap fiber instead of a glass cell. The influence of deleterious processes including energy pooling, photo-ionization, and Penning ionization on the physical features of a fiber DPAL is studied in this report. It has been theoretically demonstrated that the deleterious processes cannot be ignored in a high-powered fiber-DPAL system.

Hollow-core Optical Fiber Gas Lasers (HOFGLAS): a review [Invited]

The development of hollow core photonic crystal fibers with low losses over a broad spectral region in the near IR enabled the demonstration of a novel laser type Hollow-core Optical Fiber Gas Laser (HOFGLAS). The laser combines attractive features of fiber lasers such as compactness and long interaction length of pump and laser radiation with those of gas lasers such as the potential for high ...

Characteristics and Laser Performance of Yb-Doped Silica Large Mode Area Fibers Prepared by Sol–Gel Method

Large-size 0.1 Yb2O3–1.0 Al2O3–98.9 SiO2 (mol%) core glass was prepared by the sol–gel method. Its optical properties were evaluated. Both large mode area double cladding fiber (LMA DCF) with core diameter of 48 μm and large mode area photonic crystal fiber (LMA PCF) with core diameter of 90 μm were prepared from this core glass. Transmission loss at 1200 nm is 0.41 dB/m. Refractive index fluct...

CW-lasing and amplification in Tm(3+)-doped photonic crystal fiber rod.

We report lasing and amplification in a rod type thulium-doped photonic crystal fiber with 80 μm core diameter. The rod is pumped with a 793 nm laser diode and produces more than 20 W output power at a beam quality M(2)<1.3. The laser/amplifier has a slope efficiency of 27.8%/20.1% relative to absorbed pump power with a lasing threshold at 28.6 W. The output wavelength in the lasing configurati...

Gas Filled Hallow Core Fiber Lasers Based on Population Inversion

short): Hollow-core Optical Fiber Gas LASer (HOFGLAS) have been created, and explored in pulsed mode with C2H2 and HCN gas inside the hollow core of a kagome structured photonic crystal fiber, and nearideal efficiencies were realized for wavelengths near 1.5 μm (pump, 1 ns-pulses) and 3 μm (lasing). Improved fiber loss is realized near 3 μm to <1 dB/m. In addition, a pulsed CO2 waveguide (silve...

Passively mode-locked fiber laser based on a hollow-core photonic crystal fiber filled with few-layered graphene oxide solution.

We demonstrate a nanosecond-pulse erbium-doped fiber laser that is passively mode locked by a hollow-core photonic crystal fiber filled with few-layered graphene oxide solution. Owing to the good solution processing capability of few-layered graphene oxide, which can be filled into the core of a hollow-core photonic crystal fiber through a selective hole filling process, a graphene saturable ab...
