Abstract

We have developed an ultrabroadband regenerative amplifier with a mirrorless cavity to eliminate the limitation of bandwidth of dielectric coats on cavity mirrors. The large amount of material dispersion in the Pellin–Broca prisms that are used instead of cavity mirrors is compensated for with a hybrid technique that uses Brewster prism pairs in the regenerative amplifier and an adaptive phase controller of a liquid-crystal spatial light modulator. We obtained a 16-fs pulse width with an energy of 13 mJ, which is to our knowledge the highest energy obtained in the sub-20-fs regime by use of an adaptive phase controller.
