Indirectly LED-pumped Nd:glass regenerative amplifier
We demonstrate the first LED-pumped Nd:glass regenerative amplifier. It delivers 2 ns pulses at 1053 nm with an energy of 3.8 mJ at a repetition rate of 2 Hz. This performance is achieved using a Ce:LuAG luminescent concentrator producing 3.4 kW of optical peak power in the yellow spectral range and pumped by 3200 blue LEDs. This indirect LED pumped technology demonstrates high power-scaling capabilities and shows great potential for high energy Nd:glass laser chains.
