Area of Science:

High-power laser systems
Materials science
Optical engineering

Background:

Chirped pulse amplification (CPA) enables high-power, ultrashort laser pulses.
Laser-induced damage (LID) in optical coatings limits CPA system performance.
Current numerical methods for LID assessment are insufficient for ultrashort pulses.

Purpose of the Study:

To develop a dynamic numerical model for predicting LID thresholds in dielectric multilayer coatings.
To incorporate strong-field electronic dynamics into LID threshold calculations.
To provide a more accurate assessment of optical coating robustness for advanced laser applications.

Main Methods:

A finite-difference time-domain (FDTD) algorithm was employed.
The model incorporates electric field propagation, photoionization (Keldysh model), impact ionization, and electron heating.
Simulations were performed for bulk fused silica and multilayer dielectric mirrors and gratings.

Main Results:

The dynamic model successfully simulated LID thresholds for various optical materials and structures.
Results showed good agreement with experimental measurements.
The model captures essential physics of ultrashort pulse-material interaction, including plasma generation.

Conclusions:

The developed dynamic model offers a more accurate prediction of LID thresholds compared to static methods.
This approach is crucial for designing robust optical coatings for next-generation high-power, ultrashort pulse laser systems.
Further investigation into plasma dynamics and LID criteria for few-cycle pulses is warranted.
