Abstract

Quasi-continuous wave (cw) laser action has been demonstrated by direct diode pumping of a new extremely broadband Cr3+-doped crystal. 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.
