Optical Express is the UK's No. We adopted a single-mode, single-wavelength volume holographic grating (VHG) wavelength-stabilized wavelength laser diode (LD) as a pumping LD for an end-pumped microchip Nd:YAG and Nd:YVO 4 lasers we developed during CW and pulse operations. 38 eyes received laser treatment once, and 17 eyes required another session of YAG after. This study evaluated the effect of chitosan on dentin treatment after selective removal of caries lesions with Er:YAG laser in reducing Streptococcus mutans, as well as its effect on the performed restorations.
