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%.

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.

Red and orange laser operation of Pr:KYF4 pumped by a Nd:YAG/LBO laser at 469.1nm and a InGaN laser diode at 444nm [PDF]
, 2013 We report the basic luminescence properties and the continuous-wave (CW) laser operation of a Pr3+-doped KYF4 single crystal in the Red and Orange spectral regions by using a new pumping scheme.

Thermal-lens measurement in a side-pumped 1.3-μm Nd:YVO4 bounce laser [PDF]
, 2007 We investigated thermal-lensing effects in a side-pumped 1.3-μm Nd:YVO4 slab laser amplifier having a bounce geometry. The thermal-lens power during 1.3 μm laser action was 1.3-times larger than that without laser action.

Laser diode pumped Nd:YVO4 laser.
The Review of Laser Engineering, 1990 Having a larger stimulated emission cross section and stronger fluorescence emission, a laserdiode (LD) pumped Nd: YVO4 laser has higher efficiency and power than Nd: YAG laser.Spectral property and CW end-pumped lasing characteristics have been measured on thismaterial.
