Crystalline fiber Ho³⁺:YAG laser resonantly pumped by high-spectral-brightness laser diodes

Resonantly diode pumping of Tm:CaF2 and Tm:Ho:CaF2 lasers

“…[2][3][4][5] To reduce the thermal effect and to increase the laser efficiency the resonant pumping directly to the upper laser band was also adopted. [6,7] In present study we demonstrate for the first time the direct diode resonant pumping of room-temperature operating Tm:CaF 2 and Tm:Ho:CaF 2 ceramics. using hot pressing and hot formation technique.…”
