摘要
A tunable continuous wave （CW） low temperature operating Tm （6 at.-%）,Ho （0.6 at.-%）：YLF laser pumped by fiber-coupled diode laser is reported. The maximum output power is 4.16 W at 2073 nm by use of 30% output coupling, the slope efficiency is 33%. A tuning range from 2049 to 2081 nm is achieved with a birefringent filter （BF）. The factors that contribute to the output power and tuning range are discussed.
