Abstract

Recent developments in micro-optics offer the potential of higher power and more robust ultrafast laser technology operating at high efficiency. Results using micro-optic lenslet arrays in an ultrafast, Ti:sapphire terawatt amplifier are presented. We report a final ultrafast amplified laser mode can be shaped to within 1% of the target Gaussian with a 532nm pump energy to 800nm laser pulse energy conversion efficiency of 35% in Ti:sapphire. Focusing studies demonstrate the laser system with microlens arrays can achieve a peak intensity of 10¹⁹ W/cm². Future applications of microlens arrays in 100 terawatt and possibly petawatt peak power systems will be discussed.
