Electro-optical cavity-dumped Ce:Nd:YAG laser for aesthetic medicine

An electro-optical cavity-dumped 20 Hz Ce:Nd:YAG laser with an optimized thermal-insensitive concavo-convex cavity for aesthetic medicine was demonstrated. The pulse width remained constant at 6.0 ns. The maximum output energy and peak power were 120 mJ and 20 MW, respectively. The average output energy was very stable. The fluctuations of average output energy within 6 cycles and 10 min were 0.89% and 7.9%, respectively.

► Electro-optical cavity-dumped laser was demonstrated.
► Ce:Nd:YAG crystal was employed to increase the absorption efficiency.
► Optimized concavo-convex cavity was used to realize thermal-insensitive laser.
