A laser surgical device (10) for vaporization of a living tissue consists of an operating laser assembly (22, 24, 26, 28, 30, 32, 34), a detecting arrangement (48), and a control unit (14). The operating laser assembly generates an operating beam having a predetermined wavelength corresponding to a peak absorption wavelength of water. The detecting arrangement is adopted for detecting a condition of an operated living tissue by receiving and reviewing a signal reflected from the operated living tissue so as to produce a control signal. The control unit controls characteristics of the operating beam based on the control signal, so that the depth of vaporization of the living tissue does not exceed 15 microns to 20 microns. |
