Direct diode-pumped laser operation of Cr³⁺-doped LiInGeO₄ crystals

Quasi-continuous wave (cw) laser action has been demonstrated by direct diode pumping of a new extremely broadband Cr³⁺-doped. In contrast to previous works, where large-frame pump lasers have been employed, we have shown that low-power direct diode pumping of LiInGeO₄ is feasible, opening up the way for realizing compact and efficient laser sources for telecommunication applications.5 page(s
