- Thulium channel waveguide laser in a monoclinic double tungstate with 70% slope efficiency
[作者:van Dalfsen, K; Aravazhi, S; Grivas, C; Garcia-Blanco, SM; Pollnau, M,期刊:OPTICS LETTERS, 页码:887-889 , 文章类型: Article,,卷期:2012年37-5]
- Laser experiments were performed on buried, ridge-type channel waveguides in an 8 at.% thulium-doped, yttrium-gadolinium-lutetium codoped monoclinic double tungstate. A maximum slope efficiency of 70% and output powers u...
- Spatial optical filter sensor based on hollow-core silica tube
[作者:Ferreira, MS; Schuster, K; Kobelke, J; Santos, JL; Frazao, O,期刊:OPTICS LETTERS, 页码:890-892 , 文章类型: Article,,卷期:2012年37-5]
- A spatial optical filter based on a hollow-core silica tube is proposed. Because of the hollow-core dimensions, it is possible to obtain a periodical spatial filter ranging from 1200 to 1700 nm with a channel spacing of ...
- AlxGa1-xN-based deep-ultraviolet 320 x 256 focal plane array
[作者:Cicek, E; Vashaei, Z; Huang, EKW; McClintock, R; Razeghi, M,期刊:OPTICS LETTERS, 页码:896-898 , 文章类型: Article,,卷期:2012年37-5]
- We report the synthesis, fabrication, and testing of a 320 x 256 focal plane array (FPA) of back-illuminated, solar-blind, p-i-n, AlxGa1-xN-based detectors, fully realized within our research laboratory. We implemented a...
- Observation of microsphere movement driven by optical pulse: comment
[作者:Pozar, T; Mozina, J,期刊:OPTICS LETTERS, 页码:902-902 , 文章类型: Article,,卷期:2012年37-5]
- We show that fiber-delivered, pulsed laser propulsion of glass microspheres, as observed in a recent Letter [Opt. Lett. 36, 1996 (2011).], due to only radiation pressure cannot explain the measured maximum velocity of mi...
- Bilayer-fish-scale ultrabroad terahertz bandpass filter
[作者:Zhang, XQ; Gu, JQ; Cao, W; Han, JG; Lakhtakia, A; Zhang, WL,期刊:OPTICS LETTERS, 页码:906-908 , 文章类型: Article,,卷期:2012年37-5]
- A bilayer fish-scale metamaterial is experimentally demonstrated to function as a broad bandpass filter in the terahertz regime. The measured 3 dB-bandwidth for normal incidence is 1.13 THz with a high transmittance. The...
- High-fidelity, 160 fs, 5 mu J pulses from an integrated Yb-fiber laser system with a fiber stretcher matching a simple grating compressor
[作者:Fernandez, A; Jespersen, K; Zhu, L; Gruner-Nielsen, L; Baltuska, A; Galvanauskas, A; Verhoef, AJ,期刊:OPTICS LETTERS, 页码:927-929 , 文章类型: Article,,卷期:2012年37-5]
- Although femtosecond microjoule Yb-fiber systems are attractive because of a straightforward power scalability, they inherently suffer from a lowered pulse fidelity as a result of complex dispersion and nonlinearity mana...
- Frequency domain aperture for the gain bandwidth reduction of stimulated Brillouin scattering
[作者:Wiatrek, A; Preussler, S; Jamshidi, K; Schneider, T,期刊:OPTICS LETTERS, 页码:930-932 , 文章类型: Article,,卷期:2012年37-5]
- In this Letter, we propose a novel method based on the inhomogeneous Brillouin gain saturation to reduce the gain bandwidth significantly below its natural value. Based on our first experiments, we report a decrease of t...
