Abstract

In this work, we present a high pulse energy multi-wavelength Raman laser spanning from 1.53 um up to 2.4 um by employing the cascaded rotational stimulated Raman scattering (SRS) effect in a 5-m hydrogen (H2) -filled nested anti-resonant fiber (NARF), pumped by a linearly polarized Er/Yb fiber laser with a peak power of ~13 kW and pulse duration of ~7 ns in the C-band. The developed Raman laser has distinct lines at 1683 nm, 1868 nm, 2100 nm, and 2400 nm, with pulse energies as high as 18.25 uJ, 14.4 uJ, 14.1 uJ, and 8.2 uJ, respectively. We demonstrate how the energy in the Raman lines can be controlled by tuning the H2 pressure from 1 bar to 20 bar

Abstract

Bright, coherent soft X-ray (SXR) radiation is essential to a variety of applications in fundamental research and life sciences. So far, high photon flux in this spectral region can only be delivered by synchrotrons, free electron lasers or high-order harmonic generation (HHG) sources, which are driven by kHz-class repetition rate lasers with very high peak powers. Here, we establish a novel route toward powerful and easy-to-use SXR sources by presenting a compact experiment, in which nonlinear pulse self-compression to the few-cycle regime is combined with phase-matched HHG in a single, helium-filled antiresonant hollow-core fibre (ARHCF). This enables the first 100 kHz-class repetition rate, table-top SXR source, that delivers an application-relevant flux of 2.8*10^6 Photons/s/eV around 300 eV. The fibre-integration of temporal pulse self-compression (leading to the formation of the necessary strong-field waveforms) and pressure controlled phase-matching will allow compact, high repetition rate laser technology, including commercially available systems, to drive simple and cost-effective, coherent high-flux SXR sources., Comment: 12 pages, 3 figures

Abstract

Unraveling the scientific and technological importance of the mid-infrared (mid-IR) region remains yet a long-standing challenge. Despite the significant efforts on mid-IR light sources, development of high-energy, narrow-linewidth and compact lasers still constitutes the main obstacle towards novel spectroscopic, imaging and sensing devices. Photoacoustic modality is known as one of the most powerful tools enabling high signal-to-noise ratio gas detection and albeit its wide use in the mature near-infrared (near-IR) region, further research has to be carried out in the mid-IR in order to “unlock” its full potential. In this work, we aim on tracing CO2 based on the innovative combination of the emerging gas-filled mid-IR silica anti-resonant hollow-core fiber (ARHCF) Raman laser technology with the powerful photoacoustic modality. The laser source adopts the stimulated Raman scattering effect of H2 filled in a piece of ARHCF, to enable the generation of first-order vibrational Raman Stokes from a 1533 nm Er-doped fiber laser pump. With this configuration, a nanosecond laser pulses with micro-joule level pulse energy is achieved at ~ 4.25 μm wavelength, which is located within the strongest absorption band of CO2. The laser’s linewidth is estimated to be tens GHz level. This laser source is used to drive an in-house developed photoacoustic sensor, revealing a 1.78 ppm level CO2 detection limit in laboratory condition. This work provides a valuable reference for the development of high-sensitivity gas detectors.

The developed Raman laser has distinct lines at 1683 nm, 1868 nm, 2100 nm, and 2400 nm, with pulse energies as high as 18.25 µJ, 14.4 µJ, 14.1 µJ, and 8.2 µJ, respectively. We demonstrate how the energy in the Raman lines can be controlled by tuning the H2 pressure from 1 bar to 20 bar.

26. Single-mode, low loss hollow-core antiresonant fiber designs

Abstract

In this paper, we numerically investigate various hollow-core anti-resonant (HCAR) fibers towards low propagation and bend loss with effectively single-mode operation in the telecommunications window. We demonstrate how the propagation loss and higher-order mode modal contents are strongly influenced by the geometrical structure and the number of the anti-resonant cladding tubes. We found that 5-tube nested HC-AR fiber has a wider antiresonant band, lower loss, and larger higher-order mode extinction ratio than designs with 6 or more anti-resonant tubes. A loss ratio between the higher-order modes and fundamental mode, as high as 12,000, is obtained in a 5-tube nested HC-AR fiber. To the best of our knowledge, this is the largest higher-order mode extinction ratio demonstrated in a hollowcore fiber at 1.55 μm. In addition, we propose a modified 5-tube nested HC-AR fiber, with propagation loss below 1 dB/km from 1330 to 1660 nm. This fiber also has a small bend loss of ~15 dB/km for a bend radius of 1 cm.

27. Multioctave supercontinuum from visible to mid-infrared and bend effects on ultrafast nonlinear dynamics in gas-filled hollow-core fiber

Abstract

Broadband supercontinuum generation is numerically investigated in a Xe-filled nested hollow-core antiresonant (HC-AR) fiber pumped at 3 μm with pulses of 100 fs duration and 15 μJ energy. For a 25 cm long fiber, under 7 bar pressure, the supercontinuum spectrum spans multiple octaves from 400 nm to 5000 nm. Furthermore, the influence of bending on ultrafast nonlinear pulse propagation dynamics is investigated for two types of HC-AR fibers (nested and non-nested capillaries). Our results predict similar nonlinear dynamics for both fiber types and a significant reduction of the spectral broadening under tight bending conditions.
