Abstract

Systems and methods of high efficiency amplification of pulsed laser output for high energy ultra-short pulse laser systems are provided herein. According to some embodiments, methods for amplifying pulsed laser output for high energy ultra-short pulse laser systems include receiving pulsed laser output and amplifying the pulsed laser output by propagating the pulsed laser output through a non-silica based gain medium that has been doped with a concentration of rare earth ions, wherein the concentration of the rare earth ions within the gain medium is approximately greater than one percent by weight.

First claim

What is claimed is:

1. A method for amplifying laser pulses for ultra-short pulse laser output, the method comprising:
receiving laser pulses;
amplifying the laser pulses by propagating the laser pulses through a non-silica based gain medium that has been doped with a concentration of a rare earth ions, wherein the concentration of the rare earth ions within the gain medium is approximately greater than one percent by weight;
phase tailoring the laser pulses to reduce self-pha…
