Effect of pulse duration on microsecond-domain laser lithotripsy.

abstract：BACKGROUND AND OBJECTIVES:Nonmelanoma skin cancers, including basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), are the most common skin cancers, presenting nearly as many cases as all other cancers combined. The current gold-standard for clinical diagnosis of these lesions is histopathologic examination, a...
