Abstract—We presented a compact and efficient diode-end-pumped 1313 nm Nd:YLF laser with an effective
pump system and no additional insertion loss. The different thermal lensing effects along the and polariza-
tions in an a-cut Nd:YLF crystal were investigated. 6.2 W output power of the polarized 1313 nm laser was
obtained at the absorbed pump power of 17.5 W, corresponding to the optical-optical efficiency of 35% and the
slope efficiency of 41%.
