In the experiment, a MOPA system that consisted of a ps mode-locked oscillator, an RGA, and three-stage Nd:YAG slab amplifiers was adopted to obtain the high pulse energy output at 1064 nm, presented in figure 1. Institutional review board was not applicable for this case. With the Nd:YAG laser, the active gain medium is neodymium, which is doped into a host crystal of yttrium aluminum garnet. The control and etchant groups received no treatment and. Solid lasers use ions suspended in a crystalline matrix to produce laser light. Capsule thickening (also called “after cataract”) can happen at any time after your cataract operation from a few months to years. We have numerically analyzed the thermal effects in Nd: YLF laser rod. The aim of this study was to investigate the efficacy of the sequential combined 585 nm PDL and the 1064 nm neodymium:yttrium-aluminium-garnet laser (PDL/Nd:YAG) in the treatment of surgical scars and to evaluate the short-term effects by<i> in vivo</i> confocal microscopy (RCM) and the long-term effects by clinical assessment. Materials and methods: Medline, Cochrane Library, EMBASE and Google Scholar databases were. 6-mm diameter, 9-mm length, micro short pulse (MSP), 20 Hz, 50 mJ, 1 W). A holmium:yttrium aluminum garnet (Ho:YAG) laser is mainly used in medical surgeries such as tissue ablation and removal of urinary stones. This allows your body’s natural healing process to take over, and rebuild the damaged areas. Side Effects of Laser Treatments for Rosacea.
