High-power passively Q-switched microchip lasers produce 157-muJ pulses of 1-ns duration in a single-frequency, diffraction-limited output beam. The unfocu... JJ Zayhowski - 《Optics Letters》 被引量: 135发表: 1997年 Three-dimensional laser radar with APD arrays MIT Lincoln Laboratory is ac...
Furthermore, laser-induced electrode structures lead to improved homogeneity and fast wetting of electrodes. The use of high-power pulsed lasers transported by the fiber optic has enabled laser structuring of large electrode areas in a concise time. In recent years laser machining technology has ...
Quasi-three-level lasers have become highly efficient sources in the near and mid infrared; by direct emission or as pump sources for nonlinear conversion. Understanding their special spectroscopic properties and laser dynamics is the key to an efficient laser design and high output power, as demons...
Three-dimensional reconstruction involves estimating the 3D geometric properties of an object from its 2D image. The 3D geometric properties include 3D coordinates, the 3D orientation, and the depth for each 3D point. Three-dimensional coordinate (3 degrees of freedom) reconstruction is also referred...

Ideally, a sensor would give direct access to the intrinsic optical material properties such as polarizability and absorptivity, differentiate functional properties such as, e.g., the drug load of nano-carriers or the folding state of proteins, and allow to monitor the Brownian motion to reveal ...
Double acceptor doped Ge: A new medium for inter‐valence‐band lasers We report on intervalence‐band laser emission from Be‐ and Zn‐doped germanium crystals. The duty cycle of 10−3at a repetition rate of 1 kHz is one or... E. Bründermann,A.M. Linhart,L Reichertz,... - 《...
Gain medium the gain medium is the major determining factor of the wavelength of operation,and other properties of the laser.There are hundreds if not thousands of different gain media in which laser operation has been achieved.the gain medium is excited by the pump source to produce a ...
