High-efficiency laser-diodes-pumped microthickness Yb:Y3Al5O12 slab laser
A high-efficiency and high-power Yb:Y3Al5O12 oscillator was developed based on the microthickness slab structure with high aspect ratio to obtain one-dimensional temperature gradient and to reduce the temperature increase in the crystal. Laser output power of 257W was obtained in cw oscillation with...

| Zusammenfassung: | A high-efficiency and high-power Yb:Y3Al5O12 oscillator was developed based on the microthickness slab structure with high aspect ratio to obtain one-dimensional temperature gradient and to reduce the temperature increase in the crystal. Laser output power of 257W was obtained in cw oscillation with 42% optical conversion efficiency at a pump power of 608W. |
