Twisted clad microstructured optical fibers: revisited
Applied Physics B - Tập 117 - Trang 481-486 - 2014
M. A. Baqir, P. K. Choudhury
The paper discusses confinements corresponding to low-order sustained hybrid modes in twisted clad microstructured optical fiber with twists in the form of conducting sheath helix structure introduced at the core–clad interface and inclined at certain angles. Dispersion relations for such fiber structures are deduced under strict electromagnetic boundary conditions. Varying the angle of pitch (of ... hiện toàn bộ

Comprehensive kinetic model for electron-beam-excited XeCs+ ionic excimers
Applied Physics B - Tập 60 - Trang 391-403 - 1995
J. L. Lawless, D. Lo
A theoretical model that accounts for fundamental plasma processes leading to the formation and decay of XeCs+ ionic excimers in high-pressure electron-beam-excited Ar/Xe/Cs mixtures was developed. Numerical calculations based on the model were performed. For atmospheric gas mixtures, the model predicts an intrinsic efficiency (energy stored in upper state/energy deposited) of 18%.

High-power diode-cladding-pumped Tm3+, Ho3+-doped silica fibre laser
Applied Physics B - Tập 77 - Trang 489-491 - 2003
S.D. Jackson, S. Mossman
The fundamental characteristics of a continuous-wave high-power diode-pumped Tm3+, Ho3+-doped double-clad silica fibre laser are presented. A maximum output power of 5.2 W was measured and was generated at a slope efficiency of 42 (44)% with respect to the launched (absorbed) pump power. At the optimum length of 7 m (αeffL=2.9, where αeff is the effective absorption coefficient of the fibre and L ... hiện toàn bộ
Influence of the 61 S 0–63 P 1 resonance on continuous Lyman-α generation in mercury
Applied Physics B - Tập 113 - Trang 559-566 - 2013
Daniel Kolbe, Martin Scheid, Jochen Walz
Continuous coherent radiation in the vacuum ultraviolet at 122 nm (Lyman-α) can be generated using sum-frequency mixing of three fundamental laser beams in mercury vapor. One of the fundamental beams is at 254 nm wavelength, which is close to the 61 S 0–63 P 1 resonance in mercury. Experiments have been performed to investigate the effect of this one-photon resonance on phase-matching, absorption ... hiện toàn bộ
Khoang nguyên tử với gương gây ra bởi ánh sáng Dịch bởi AI
Applied Physics B - Tập 48 - Trang 517-523 - 1989
V. I. Balykin, V. S. Letokhov
Chúng tôi xem xét khả năng tạo ra một khoang nguyên tử dựa trên sự phản xạ của các nguyên tử từ một trường laser. Các tham số chính của khoang như vận tốc nguyên tử tối đa và tối thiểu, độ ổn định của khoang, sơ đồ bơm nguyên tử, mật độ nguyên tử tối đa đã được xác định. Đã chỉ ra rằng một sự suy biến cao của các nguyên tử (≫1) có thể đạt được trong khoang như vậy.

Quantum coherence in electrically pumped organic interferometric emitters
Applied Physics B - Tập 128 - Trang 1-6 - 2021
F. J. Duarte, T. S. Taylor
Electrically pumped organic semiconductors have been demonstrated to yield nearly diffraction-limited beam divergences and high-visibility double-slit interferograms characteristic of laser emission. This coherent emission has been measured and quantified in detail but no explanation has been advanced on the origin of this emission. Here, the origin of this emission is explained in terms of probab... hiện toàn bộ
Stable single axial mode operation of injection-seeded Q-switched Nd:YAG laser by real-time resonance tracking method
Applied Physics B - Tập 114 - Trang 579-584 - 2013
Xiaozhen Xu, Jean-Claude Diels
A simple real-time resonance tracking method is described and experimentally demonstrated for stable single axial mode operation of an injection-seeded Q-switched Nd:YAG laser. We have achieved stable single axial mode operation with mW of seeding power in noisy environment over hours. The mode selectivity dependence on finite Q-switch opening time is demonstrated and quantitatively modeled for Q-... hiện toàn bộ
Photoacoustic system for on-line process monitoring of hydrogen sulfide (H2S) concentration in natural gas streams
Applied Physics B - Tập 85 - Trang 315-321 - 2006
A. Varga, Z. Bozóki, M. Szakáll, G. Szabó
A dual-channel hydrogen sulfide (H2S) concentration measuring system based on photoacoustic spectroscopy is described. The system uses a single-mode, fiber-coupled, room-temperature-operated, telecommunication-type diode laser with a wavelength of 1574.5 nm and an output optical power of 40 mW and two identical resonant photoacoustic cells to achieve minimum detectable H2S concentration at 0.5 ppm... hiện toàn bộ
Investigation of Tm3+/Yb3+ co-doped germanate–tellurite glasses for efficient 2 µm mid-infrared laser materials
Applied Physics B - Tập 124 - Trang 1-9 - 2018
Aoju Dou, Lingling Shen, Ning Wang, Yangjian Cai, Muzhi Cai, Yanyan Guo, Feifei Huang, Ying Tian, Shiqing Xu, Junjie Zhang
The Tm3+/Yb3+ co-doped germanate–tellurite glasses with good thermal properties were prepared. Based on the absorption spectra and the Judd–Ofelt theory, the J–O intensity parameters (Ω t ), radiative transition probability (276.78 s− 1), fluorescence lifetime (3.89 ms), absorption and emission cross sections ( $${\sigma _{\text{e}}}$$  = 1.35 × 10− 20 cm2) were calculated. The ~ 2 µm mid-infrared... hiện toàn bộ
