<p>A variable pulse width lasing device (10) for selectively reducing the amount of laser energy provided during a surgical procedure, is described. The device includes a central processing unit (24), a laser resonator (16), pulse width detector (66), and a pulse modulator (14). The central processing unit (24) provides a switch activation command to the modulator (14). The modulator also receives a laser pulse produced by the laser resonator (16) 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 (78) at a selected pulse width and energy level.</p> |
