Variable pulse width lasing device

摘要

A variable pulse width lasing device for selectively reducing the amount of laser energy provided during a surgical procedure is described. The device includes a central processing unit, a laser resonator, pulse width detector and a pulse modulator. The central processing unit provides a switch activation command to the modulator. The modulator also receives a laser pulse produced by the laser resonator which has an initial pulse width and a wavelength which is compatible for transmission through an optical fiber. The modulator varies the width of the laser pulse for providing an output pulse at a selected pulse width and energy level.
