Selected Publications

ASLD (Advanced Software for Laser Design) is used worldwide for the simulation and optimization of solid-state lasers, amplifiers, and complex photonic systems. Developed through research collaborations between ASLD and leading academic institutions, the software has contributed to numerous scientific, industrial, and aerospace projects.

The publications below are divided into two groups. ASLD Development & Research contains papers describing the software, its underlying algorithms, and research conducted by the ASLD team and collaborators. Research, Industry & Aerospace Applications contains publications and project reports from universities, research organizations, industrial partners, and space-related programs that have used ASLD for laser design and simulation.
