LED-pumped picosecond and nanosecond laser amplifiers
A light-emitting diode is a low-energy-density light source, which is usually disadvantageous for building a high-gain laser amplifier. Here, we report LED-pumped nanosecond 4-pass and picosecond regenerative Nd:YAG laser amplifiers with output peak powers of 11 and 60MW, respectively, at 1064nm. With the slight broadband LED pumping, the measured stability of the pulse energy is within 3% over 40 minutes for the regenerative amplifier.
