“…The HC-PCF system provides narrowband VUV pulses down to 141 nm with spectral densities exceeding 10 nW/GHz using only 100 mW of input power delivered from a simple air-cooled compact laser. The efficiency of the system might potentially be further increased using pressure gradients or tapered HC-PCFs [15] to improve phase matching. Moreover, the average power in the VUV could be upscaled by using pump lasers with higher repetition rates [16].…”

Many fields such as bio-spectroscopy and photochemistry often require sources of vacuum ultraviolet (VUV) pulses featuring a narrow linewidth and tunable over a wide frequency range. However, the majority of available VUV light sources do not simultaneously fulfill those two requirements, and few if any are truly compact, costeffective and easy to use by non-specialists. Here we introduce a novel approach that goes a long way to meeting this challenge. It is based on hydrogen-filled hollow-core photonic crystal fiber pumped simultaneously by two spectrally distant pulses. Stimulated Raman scattering enables the generation of coherence waves of collective molecular motion in the gas, which together with careful dispersion engineering and control over the modal content of the pump light, facilitates cooperation between the two separate Raman combs, resulting in a spectrum that reaches deep into the VUV. Using this system, we demonstrate the generation of a dual Raman comb of narrowband lines extending down to 141 nm using only 100 mW of input power delivered by a commercial solid-state laser. The approach may enable access to tunable VUV light to any laboratory and therefore boost progress in many research areas across multiple disciplines.

Photonic crystal fiber (PCF) beside heptagonal cladding with elliptical rotated-hexa curved center are talked about for terahertz (THz) waveguide. It is recognized that a successful effective material loss (EML) of 0.0076 cm-1 has been accomplished at 1 THz working recurrence. By utilizing the photonic crystal fiber PCF) concept, all reenactment comes about have been gotten with the limited finite element method (FEM) and perfectly match layer (PML) border conditions based on COMSOL Multiphysics computer apparatuses. This PCF fiber uncovers EML of 0.0076 cm−1, with expansive an effective area (EA) of 5.95×10-8 m2 and stream of control within the center locale of 90% at 1 THz. Besides, around pivotal optical directing viewpoints like as restriction misfortune, scattering, methodology, power fraction (PF) and effective mode area (EMA) have been too considered briefly. It is expected that the mentioned PCF waveguide will offer a significant improvement over existing design for communication field. Maintaining the typical principles for all the optical constraints suggests that the anticipated PCF can proficiently be pragmatic in multichannel communication and some other domains of the THz technology.

“…The intersection point between the Stokes efficiency curve and pump one also seem to be on the Stokes efficiency straight line of 50%, like the case of gas pressure change. These give us another simple way to enhance the Raman generation efficiency instead of using other complex Raman generation system with special hollow fibre structure [14,15] or tailor polarization [16].…”

In this paper, we study of the coherent Stokes generation in a transient Raman regime by Hydrogen gas-filled hollow-core photonic crystal fibres (HC-PCFs) configuration. The temporal and spatial evolution of the pump and Stokes field envelopes as well as the coherence and population inversion is numerically observed. The influence of the pump pulse width and gas pressure on the energy exchange along fiber and Stokes generation efficiency is investigated.
