Rapid growth and ultra-precision machining of large-size KDP (KH2PO4) crystals with high laser damage resistance are tough challenges in the development of large laser systems. It is of high interest and practical significance to have theoretical mod

Interactions of liquid crystals (LC’s) with polarized light have been studied widely and have spawned numerous device applications across wide regions of the electromagnetic spectrum. To date, little is known about the effect of incident light pola

Laser systems capable of delivering energetic nanosecond pulses with large incoherent bandwidth spanning more than 10 THz are currently under development for the study of laser–plasma instabilities. A consequence of such a spectrum is random intens

A laser pulse impinging on the surface of an optical component can interact with particles, such as contamination debris, to produce a scattered electric field, which, either by itself or combined with the incident laser field, coherently can signifi

The interactions of microparticles of different materials located on the surface of a multilayer dielectric mirror with intense 1053-nm laser pulses of varying fluence and duration (10 and 0.6 ps) are investigated. The particles caused localized inte

Among the fundamental mechanisms of laser-induced damage of optical multilayers, multiphoton absorption is frequently addressed. The two most common models (the fixed-multiphoton-order model and the Keldysh model) of nonlinear absorption are invalid

Multiphoton absorption substantially contributes to the initiation of laser damage of optical coatings by ultrashort laser pulses. Here we report a simulation approach to fix some assumptions of the traditional models violated at near-damage-threshol

Laser-induced damage remains a key limiting factor for laser system performance. This presentation will review three main issues associated with laser-induced damage: (1) The processes involved leading to material modification, (2) the damage-initiat

This work investigates the interaction of 10-ps and 0.6-ps, 1053-nm laser pulses with ≈40 um-diam microparticles located on the surface of a multilayer dielectric mirror. Resulting morphology was examined as a function of fluence and number of puls
