Frequency-resolved measurement of the emission from a Eaman free electron laser under superradiation condition by a microwave grating spectrometer are presented.
For grating in the optical pick-up head, the compensability between the longitudinal and transverse error practical references on the manufacture of grating.
A new dynamic model is developed for simulating the widely tunable grating assisted codirectional coupler with rear sampled grating reflector (GCSR) lasers.
Well equipped, these instruments feature: multiple entrance and exit ports, high precision wavelength drives, extended range operation, Echelle, and oversize grating mounting capabilities.
The wavelength division effect of grism in a multi-wavelengths optical system is discussed, the grism consist of a tranditional optical prism and a diffraction optical phase grating.
As a practical example, an astigmation corrected scanning flat holographio concave grating (SFHCG) is designed and some results of the numerical and optical experiments are given.
According to the theory of scalar diffraction, first, the equipollence of spatial distribution of the plane-wave interferential field and parallel projective sine grating is discussed.
Still, she spent that Friday morning grating cheese...and greasing a pan...and laying in macaroni because her eldest daughter was sick, and Stella could no longer sit by and do nothing.
Douglass' recorded laughs also took out some of the audience response ticks that are a normal part of live performance, but can register as disorienting and grating to viewers at home.
