英文摘要：

We study the laser performance of c-cut Nd：Lu0.99La0.01VO4 crystal end-pumped by optical fiber coupled semiconductor laser. Based on the spectral characteristics of the 4F3/2→4F11/2 energy level transition and the threshold conditions of four-level laser system, the experimental conditions to generate single- and dual-wavelength laser at 1068 nm and 1085 nm are calculated theoretically. The output characteristics of the single-wavelength laser at 1068 nm and 1085 nm generated in free running of this crystal are studied experimentally, and an Fabry-Perot etalon with sub-terahertz free spectral range is used to adjust the gain competition of two laser oscillating wavelengths at 1068 nm and 1085 nm. The stabilized and balanced output of multi watt continuous dual-wavelength emission with a frequency offset of 4.4 THz is realized.
