Abstract Cerium-doped lutetium-yttrium oxyorthosilicate (Ce:LYSO) is a well-known single crystal scintillator used in medical imaging and security scanners. Recent development of high power UV LED, matching its absorption band, questions the possibil

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 develope

We report the development of a high-brightness, high-power Ce:YAG luminescent concentrator pumped by 2240 blue LEDs in quasi-continuous wave operation (10 µs, 10 Hz). Using light confinement and recycling in the three space dimensions, the parallele

Transition metal-doped gain media such as Ti:sapphire, Cr:LiSAF and Alexandrite are the most appropriated crystals for femtosecond laser chains with pulse duration below 100 fs. However, because of a low gain and an absorption band in the green/red r

Since the early 2000s, light-emitting diodes (LEDs) have simultaneously known a dramatic improvement of their performance and a drastic cost reduction making LEDs the most efficient and affordable light sources for lighting. However, their irradiance
