Embodiment approach
[0040] On the basis of the above embodiments, a Q-switching element can be inserted into the resonant cavity to obtain pulsed laser output.
[0041] On the basis of the above embodiments, Nd:YLF crystal, Nd:KGW crystal, etc. can be selected as the gain medium 7 to compensate for the astigmatism formed by the resonant cavity.
[0042] On the basis of the above embodiments, resonant cavities with other structures can be selected, such as V-shaped cavity, 6-mirror cavity, etc., to compensate each other with the astigmatism of the thermal lens of the gain medium 7 .
