Abstract
The present invention provides a laser apparatus for medical treatment using pulse trains, in which the skin is cooled to a given temperature and then one or more laser pulses are applied to a to-be-treated region at specific intervals, thereby alleviating a pain associated with a skin disease and activating a dermis layer. According to the present invention, a pain caused during the treatment process is alleviated by using laser pulse trains and a cooling unit, and heat energy is transferred to only a dermis layer of a to-be-treated region without eliminating an epidermis layer of the to-be-treated region, thereby remarkably improving the treatment recovery period and the frequency of treatments as compared to the conventional treatment method.
