High-order wavefront aberrations due to a laser-induced breakdown spark in still airApplied Optics - Tập 59 Số 25 - Trang 7510-7520 - 2020
M. Nguyen, Zareb A. Noel, Jonathan Wells, R. Mark Rennie
Experimental measurements of the wavefronts of the light from a laser-induced breakdown (LIB) spark in stationary air are presented for the full range of angles between the LIB laser and wavefront sensor up to 90°. The wavefront data are compared to measurements of the spark shape and position acquired from simultaneous photographic images of the spark. The results show that the aberrations from t...... hiện toàn bộ

Silica-based photonic crystal fiber infiltrated with 1,2-dibromoethane for supercontinuum generationApplied Optics - Tập 60 Số 24 - Trang 7268-7278 - 2021

This study proposes a photonic crystal fiber (PCF) made of fused silica glass with the core infiltrated with 1,2-dibromoethane (C2H4Br2) as a new source of supercontinuum light pulses. Due to the modifications of the PCF’s structure geometry, a number of computer simulations investigating their optimized structures has been carried out. This aimed at achieving flat near-zero dispersion and zero di...... hiện toàn bộ

Gaussian Light Beams with General AstigmatismApplied Optics - Tập 8 Số 8 - Trang 1687-1693 - 1969
J. A. Arnaud, H. Kogelnik
This paper considers the propagation and diffraction of coherent light beams through nonorthogonal optical systems such as sequences of astigmatic lenses oriented at oblique angles to each other. The fundamental (gaussian) mode has elliptical light spots in each beam cross section and ellipsoidal (or hyperboloidal) wavefronts near the axis. It is found that the orientation of the light spot differ...... hiện toàn bộ
