Embodiment Construction
[0033] In order to solve the problem that the Kerr lens mode-locking in the prior art cannot be self-started when the wide-spectrum sub-100fs mode-locking pulse output is realized, and the mode-locking of the Kerr lens is affected by the environment for a short time and after the mode-locking is lost It is also necessary to give external disturbances to re-establish mode-locking and other issues. The present invention proposes a Kerr lens self-mode-locking Yb:LYSO (Yb:LuYSiO 5 Ytterbium-doped lutetium-yttrium silicate) laser. This Yb:LYSO laser not only realizes self-starting Kerr lens mode-locking for the first time, but also obtains a femtosecond pulse output with a pulse width of 61 fs, which significantly shortens the pulse width, and compared to The existing Kerr lens mode-locked laser realizes self-starting and long-term stable operation.
[0034] like figure 1 As shown, in a typical embodiment of the present invention, the laser includes a pump source 10, a laser crys...
