The slab geometry laser - Part I: Theory

Abstract

Abstract-Slab geometry solid-state lasersoffer significant performance improvements over conventional rod geometry lasers. We present a detailed theoretical description of the thermal, stress, and beam propagation characteristics of a slab laser. Our analysis includes consideration of the effects of the zig-zag optical path which eliminates thermal and stress focusing and reduces residual birefringence. S

Comparative Study of the Birefringence in Photonic Crystal Fiber Lasers

“…[4] is necessary for determining the radially varying index of refraction d d n T , and the calculate stresses. By using Equations (1)- (3), Abouricha et al [4] demonstrated that the temperature expressions of the stress components can be written as: [1] [8] ( ) ( ) ( ) ( )…”

Diode Pumped Planar Waveguide/Thin Slab Solid-State Lasers

“…How to remove the waste heat and reduce the thermal effects efficiently usually are main considerations in the design of high average power systems. In related articles [20], consequences of thermal and thermomechanical effects have been discussed for slab lasers and amplifiers. The analyses of nonlinear thermal effects in slab lasers are also presented in ref.…”

Synchronization of sub-picosecond electron and laser pulses

“…Forced gas or low dielectric constant liquid cooling of the crystal in the cavity could be considered. Techniques of correcting thermal lensing utilized by optical slab amplifier designers may also be applicable in some modified form [7].…”
