AlGaInN LED Pump System for Ti:Sapphire Lasers

High-power AlGaInN LEDs are of interest for pumping of Ti-sapphire lasers. In this regard, comprehensive studies of the power and spectral’ characteristics of LEDs in short-pulse modes used to laser pump were carried out. The energy capabilities and spectral properties of LED excitation of Ti-Sapphire were revealed. Designs of LED arrays and a laser head have been developed, the distribution of pumping in the active element have been simulated.
