Abstract: A spectra shaping apparatus for chirped pulse amplification (CPA): uses a spectrum decomposing system with CTSI construction, a spectrum synthesizing system with CTSI structure that is optically symmetrical to the decomposing structure, and a spectrum shaping system including an aperture and a planar reflector for spectrum shaping function design. The apparatus accomplishes the following functions: firstly decomposing the spectrum of a chirped temporal pulse laser to a spectral domain; then shaping the spectrum in the spectral domain; finally synthesizing un-shiftily this shaped spectrum in the spectral domain into a temporal chirped pulse with a designed shape. The apparatus has the feature of fabricating easy, compacting the structure, requiring less space, and cheap in cost etc., which it can be the different types of configuration for different circumstance application, which it can be not only utilized in a general laser spectrum shaping and spectrum modulation, but also can be utilized for a high energy and ultra-high peak-power laser system in chirped pulse amplification with a large caliber and with a chirped pulse bandwidth of a few nanometers.

Abstract: A spectral imaging system for collecting spectral information of a two dimensional heterogeneous objects while in motion relative to the imaging system without the use of a spectrograph, filters or any dispersive optics. The system includes a pulsed light source tunable in wavelength for producing short pulses of wavelength tuned light at a plurality of selected narrow band wavelengths within a spectral range and one or more optical components for conveying or directing the short pulses of light to a two dimensional region that is substantially stationary with respect to the imaging system and through which the two dimensional target is moving. The system also includes a many pixel camera synchronized with the tunable pulsed light source. The camera is adapted to detect light in the selected narrow band wavelengths produced by the tunable pulsed light source and reflected from or transmitted through the two dimensional target in motion relative to the imaging system and to provide image frame information with each frame at a defined wavelength band. A processor processes information from said tunable light source and said camera and to produce multi-spectral images of the target.
