All-Fiber Gas Raman Laser by D2-Filled Hollow-Core Photonic Crystal Fibers

چکیده
We report here an all-fiber structure tunable gas Raman laser based on deuterium-filled hollow-core photonic crystal fibers (HC-PCFs). An cavity is fabricated by fusion splicing a 49 m high-pressure HC-PCF with two solid-core single-mode at both ends. When pumped pulsed fiber amplifier seeded diode 1.5 ?m, lasers ranging from 1643 nm to 1656 are generated. The maximum output power ~1.2 W conversion efficiency of ~45.6% inside the cavity. This work offers alternative choice for operating 1.6–1.7 ?m band.

Partially liquid-filled hollow-core photonic crystal fiber polarizer.
A compact fiber polarizer is demonstrated by the filling of selected air holes of a hollow-core photonic crystal fiber (PCF) with a liquid. The liquid-filling results in an asymmetric waveguide structure, leading to a large polarization dependent loss. A 6 mm long ethanol-filled PCF exhibits a polarization extinction ratio of ∼18 dB over a wavelength range from 1480 nm to 1600 nm.
متن کاملHollow core photonic crystal fiber as a reusable Raman biosensor.
We report that a single hollow core photonic crystal fiber (HC-PCF) can be used for repetitive characterization of multiple samples by Raman spectroscopy. This was achieved by integrating the HC-PCF to a differential pressure system that allowed effective filling, draining and re-filling of samples into a HC-PCF under identical optical conditions. Consequently, high-quality and reliable spectra...
متن کاملHollow core photonic crystal fiber based viscometer with Raman spectroscopy.
The velocity of a liquid flowing through the core of a hollow core photonic crystal fiber (driven by capillary forces) is used for the determination of a liquid's viscosity, using volumes of less than 10 nl. The simple optical technique used is based on the change in propagation characteristics of the fiber as it fills with the liquid of interest via capillary action, monitored by a laser sourc...
متن کاملArc fusion splicing of hollow-core photonic bandgap fibers for gas-filled fiber cells.
The difficulty of fusion splicing hollow-core photonic bandgap fiber (PBGF) to conventional step index single mode fiber (SMF) has severely limited the implementation of PBGFs. To make PBGFs more functional we have developed a method for splicing a hollow-core PBGF to a SMF using a commercial arc splicer. A repeatable, robust, low-loss splice between the PBGF and SMF is demonstrated. By filling...
متن کاملTunable frequency-up/down conversion in gas-filled hollow-core photonic crystal fibers.
Based on the interplay between photoionization and Raman effects in gas-filled photonic crystal fibers, we propose a new optical device to control frequency conversion of ultrashort pulses. By tuning the input-pulse energy, the output spectrum can be either down-converted, up-converted, or even frequency-shift compensated. For low input energies, the Raman effect is dominant and leads to a reds...
