Evaluation of the XeCl beam quality on the Stokes beam parameters
Optics Communications, 1996Abstract The advantages of applying phase-unifying unstable cavities to excimer lasers for the production of multiple wavelengths by stimulated Raman scattering (SRS) have been evaluated. A XeCl laser has been fitted either with a phase-unifying (PU) unstable cavity, or with a conventional hard-edge unstable cavity, and SRS in high pressure H 2 has ...

Beam quality evolution of vortex beam with phase distortion
Optik, 2018Abstract Based on the generalized Huygens Fresnel principle, the propagation equation of fundamental Gaussian vortex beam with phase distortion is derived. To quantitatively analyze the influence of random phase distortion on the quality of vortex beam, the variance of light intensity relative deviation is proposed as the evaluation parameter.

Quality assurance of beam tracking
2009Quality assurance of beam delivery is very important for reliable external beam radiotherapy. Especially dynamical irradiation (e.g. intensity modulated radiotherapy, active scanning, beam tracking, etc.) which changes parameters of mechanical devices or electronics during the irradiation has to be [for full text, please go to the a.m. URL]
