We experimentally demonstrated a dual-wavelength independently mode-locked Yb:YAG ceramic laser in a single cavity. Dual-wavelength mode locking at 1033.6 and 1047.6 nm was operated simultaneously in one beam. Each pulse width was measured to be approximately 380 fs using an autocorrelator. The spectral widths were 4.50 nm centered at 1033.6 nm and 3.08 nm centered at 1047.6 nm. To the best of our knowledge, this is the first dual-wavelength mode locking achieved in Yb-doped solid-state lasers.
我们通过实验证明了在单个腔内实现双波长独立锁模的Yb:YAG陶瓷激光器。在一束光中同时实现了1033.6和1047.6 nm的双波长锁模。使用自相关仪测得每个脉冲宽度约为380 fs。光谱宽度在1033.6 nm处为4.50 nm，在1047.6 nm处为3.08 nm。据我们所知，这是掺镱固态激光器中首次实现双波长锁模。
