Abstract
Dermatological systems and methods for providing a therapeutic laser treatment of tissue having poor chromophore selectivity using a laser source having a grating element to provide laser light having reduced linewidth. In some embodiments, the linewidth is reduced by at least half compared to the linewidth that would be provided in a system without the grating filter element. The linewidth may be reduced in some cases to 500 GHz or less, 300 GHz or less, or 200 Hz or less.
