Embodiment Construction

[0021] The accompanying drawing is a schematic diagram of the control of the pulsed laser beam controlled by the radial step distance of the present invention, which is a specific embodiment of the present invention.

[0022] The device of the embodiment comprises a pulse generator (1), a stepper motor pulse power supply (2), a stepper motor (3), an encoder (4), a signal detector (5) or a gate (6) and a laser generator (7). As shown in the attached picture.

[0023] The working process of the device is that after the device is started, the pulse generator (1) sends a pulse signal to the laser generator (7), and the laser head of the laser generator (7) sends a pulsed laser beam, and the laser beam acts on the living body. Depends on the width of the pulse square wave. The pulse signal sent by the pulse generator (1) controls the enabling input of the stepper motor pulse power supply (2) to make it a high level, locking the stepper motor pulse power supply (2) without output, ...

Abstract

The invention relates to axial depth control of laser beams, in particular to control of a laser beam emitted and stopped to be emitted by a laser beam of a pulse laser through the radial stepping distance of the laser head. The invention provides a device for controlling a pulse laser beam through a radial stepping distance. The device comprises a pulse generator, a laser generator, a stepping motor pulse power supply, a stepping motor, an encoder, a signal detector and a disjunction gate element. The invention aims to solve the technical problem that the conventional pulse laser beam cannot be generally applied to the treatment aspects of tissue cutting, ablation and excision of organisms. Control of the laser beam cutting depth concerns the life safety.

Description

technical field [0001] The present invention relates to the axial depth control of the laser beam, more specifically, relates to the radial stepping distance of the laser head controlled by the laser head of the pulse laser to emit and stop emitting the laser beam. The invention is mainly used for laser beam cutting, ablation and resection of biological tissues. Controlling the cutting depth of a laser beam is life-threatening. Background technique [0002] The depth control of the laser beam when processing objects depends on the energy density (temperature) and action time of the laser beam. When the energy density of the laser beam is determined, its action time is the main variable parameter to control the depth. The depth control of the pulsed laser beam is the width of the pulse in one cycle. The width of the pulse is an intuitive representation of the time variable parameter. [0003] The application of pulsed laser beams in the industrial field, including various...
