1. Characterization of Beam Quality by the 'Power-in-the-Bucket'

Author

Boris Ya Zel'dovich, Derrek R. Drachenberg, Sergiy Kaim, Leonid B. Glebov, and Sergiy Mokhov

Subjects
Physics, business.industry, Radius, Characterization (mathematics), Power (physics), Optics, Physics::Accelerator Physics, Beam shape, M squared, Laser beam quality, Atomic physics, business, Beam (structure), Dimensionless quantity
Abstract

Beam quality is described by “bucket-f” radius, r_f, and angular radius θ_f, both encapsulating fraction f of total beam power. Dimensionless product r_f*θ_f/λ depends on f and on beam shape.

Abstract

Optical losses vary with detuning from Bragg resonance due to variation of stored optical power inside grating. Additional modulation of absorption coefficient causes asymmetry in detuning dependence of losses. Experiments confirm analytic theory.

Abstract

Beam quality parameter Mx2 for Gaussian and super-Gaussian beams distorted by self-phase modulation is calculated analytically. Super-Gaussian beam demonstrates more stable behavior with propagation through Kerr media in comparison with Gaussian one.
