Abstract
Here, we demonstrate a broadband tunable (Lu0.0541Tm0.0548Gd0.8911)3Ga3O12 (Tm:LuGGG) laser in-band pumped by a homemade 1645-nm Er:YAG laser. A maximum average output power of 0.7 W at 1997 nm is obtained with a slope efficiency of 46.3%. We also demonstrate a continuously tuning output ranging from1854 to 2066 nm with a tuning coverage of 212 nm. The results indicate that the Tm:LuGGG crystal is an excellent laser medium for high-efficient broadband light generation, which may help to explore potential applications in ultrafast lasers.Description
