Yellow whispering-gallery-mode lasing from amorphous fluoride microspheres
Abhishek Sureshkumar, Jonathan Demaimay, Georges Perin +7
Compact, low-noise coherent light sources in the visible remain challenging due to limited gain platforms and inefficient pumping. We report a new route to visible microlasing base…
Ho3+-doped CALGO crystals for high-power ultrafast 2.1-μm lasers
Anna Suzuki, Pavel Loiko, Weichao Yao +8
Ho3+-doped disordered CaAlGdO4 (CALGO) crystals have recently emerged as a promising gain material platform for next-generation high-power ultrafast 2.1-μm laser systems. This las…
Resonantly Pumped Tunable Tm,X:CaF2 Lasers: Effect of Buffer Ions (X = Y, La, Gd, and Lu)
Dominika Popelová, Karel Veselský, Pavel Loiko +5
We report on the eye-safe laser performance of Tm3+-doped calcium fluoride crystals, modified with optically inactive "buffer" cations (Y3+, Lu3+, Gd3+, and La3+), under in-band di…
Yellow stimulated emission from Dy-doped silica glass microspheres
Abhishek Sureshkumar, Jonathan Demaimay, Georges Perin +9
Dy-doped silica glass whispering gallery mode microspheres are fabricated by fiber fusion splicing. They present an almost ideal spherical morphology with a radius ranging f…
