Diode-pumped Yb:GSO femtosecond laser
Optics Express, 2007 Compact femtosecond laser operation of Yb:Gd(2)SiO(5) (Yb:GSO) crystal was demonstrated under high-brightness diode-end-pumping. A semiconductor saturable absorption mirror was used to start passive mode-locking. Stable mode-locking could be realized near the emission bands around 1031, 1048, and 1088 nm, respectively.

Diode pumped yellow dysprosium lasers
Optics Express, 2012 First operation of the 4F₉/₂ → 6H₁₃/₂ laser transition in dysprosium doped yttrium aluminum garnet is reported. Efficient room temperature operation at 583 nm was obtained using 447 nm GaN diode lasers pumps. Gaussian single-mode operation was demonstrated with a non-optimized slope efficiency of 12%.
