“…For energies reaching the mJ range [13,14] and the J range [15], some papers reported transverse pumping of Cr:LiSAF with flashlamps at low repetition rates, with the wellknown drawbacks of theses pump sources (stability and lifetime). Pump pulsed operation with laser diodes were reported [16][17][18][19] including complex transverse pumping configuration including 4 laser diode stacks at 690 nm (675 W peak power each) for a total pump energy of 200 mJ during 74 µs at 10 Hz : this led to 47 mJ pulses of 300 ns in Q-switched operation in multimode operation [16]. Pulsed pumping of Cr:LiSAF with laser diodes has also been demonstrated at higher repetition rates (kHz) but with lower energies [17].…”

We developed a light-emitting diode (LED)-pumped Cr:LiSAF laser operating in Qswitched and cavity-dumped regimes. The laser produces 1.1 mJ pulses with a pulse duration of 8.5 ns at a repetition rate of 10 Hz on a broad spectrum centered at 840 nm with a full width at half maximum of 23 nm. After frequency tripling in two cascaded LBO crystals, we obtained 7 ns pulses with an energy of 13 µJ at 280 nm and with a spectral width of 0.5 nm, limited by the spectral acceptance of the phase matching process. By rotating both LBO crystals, UV emission is tuned from 276 nm to 284 nm taking advantage of the broad infrared spectrum of the Cr:LiSAF laser.

The LED-pumping technology is used for the first time, to the best of our knowledge, to develop a complete master oscillator power amplifier (MOPA) system including a multipass amplifier. A pumping head using an original slab architecture is developed integrating a Cr:LiSAF slab pumped by 2112 blue LEDs via a Ce:YAG luminescent concentrator. The slab configuration enables the reaching of a large number of passes—up to 22—together with access to efficient cooling, allowing for a repetition rate scale up. For 22 passes, the amplifier delivers pulses with energy up to 2.4 mJ at 10-Hz repetition rate with a gain of 4.36 at 825 nm. A complete study of the MOPA is described, concluding in nearly constant performances versus the repetition rate, up to 100 Hz.
