Abstract
926â¯nm laser operation in a Nd:GdNbO4 crystal based on quasi-three-level 4F3/2â¯ââ¯4I9/2 transition is reported, for the first time to our best knowledge. An average output power of 393â¯mW at 926â¯nm under 879â¯nm LD pumping is obtained with a slope efficiency of 33.3% and an optical-to-optical efficiency of 26.0%. The slope efficiency with respect to absorbed pump power is estimated to be 47.7%. Comparison between output characters of 926â¯nm laser under direct and indirect pumping is conducted. The average output power at 926â¯nm under 808â¯nm LD pumping reaches 305â¯mW with an optical-to-optical efficiency of 16.1%.
