“…They developed a tunable source in the UV based on a cavity dumped LED-LCpumped Cr:LiSAF [58]. Next, they demonstrated a LED-LC-pumped femtosecond regenerative amplifier [59] and a first Master Oscillator Power Amplifier (MOPA) based on two LED-pumped Cr:LiSAF [60]. In all cases, the laser systems were able to produce mJ pulses.…”

In the past, there were limited efforts to use light-emitting diodes (LEDs) for pumping solid-state lasers. However, these attempts were overshadowed by the introduction of laser diodes, which offered more favourable pumping conditions. Nevertheless, recent advancements in high-power LEDs, coupled with the utilisation of luminescent concentrators (LC), have paved the way for a novel approach to pump solid-state lasers. The combination of LEDs and LC in this LED-LC system presents several advantages, including enhanced ruggedness, stability, and cost-effectiveness compared to other laser pumping methods. This review explores the various techniques employed to pump solid-state lasers using LED-LC as a pump source, along with improvements made to enhance the brightness of LEDs in this context.

The work is devoted to the creation and study of high-power AlGaInN LED source with emission wavelengths (460–480) nm for pumping of solid-state lasers. The electrical, spectral, power and thermal characteristics were studied in a wide range of currents, continuous and pulsed modes. The design of LED matrices, which provides a tight “packing” of LEDs, their electrical commutation, efficient heat removal and a power supply for a wide pulse range has been proposed. The developed emitter comprises the most powerful and efficient to date LE Q8W (Osram) LEDs and is intended primarily for pumping Ti:Sapphire laser, the absorption band of which is well matched with the emission spectrum of the used LEDs. The achieved optical pumping power density in the pulsed mode is ~25 W/mm2, which corresponds to the lasing threshold.
