Embodiment Construction

[0030] It can be seen from the background art that there is a problem in the prior art that the actual laser power does not match the required laser power, and it is easy to cause adverse effects on the use effect of the laser device.

[0031] After analysis, it is found that when the excitation voltage provided to the xenon lamp remains unchanged, the luminous efficiency of the xenon lamp will decrease after aging, resulting in a decrease in its brightness, which will result in a decrease in the single pulse energy of the laser emitted by the crystal, resulting in a decrease in the actual laser power of the laser device. Laser power settings do not match. In order to make up for the problems caused by the aging of the xenon lamp, it is necessary to increase the excitation voltage value applied to the xenon lamp to increase its luminous efficiency and increase the luminous brightness, thereby compensating for the adverse effect of the dimming of the xenon lamp brightness on the...

Abstract

The invention relates to a laser device and a laser power monitoring feedback method. The laser device comprises a laser emitter, an excitation source, a transmission and reflection mirror, a power sensor and a power feedback controller, wherein the excitation source is connected with the laser emitter, the transmission and reflection mirror is arranged on a light path of laser emitted from the laser emitter and is used for dividing the laser into reflection laser and transmission laser which are transmitted along different directions, the power sensor is arranged on a light path of the reflection laser and is used for acquiring reflection laser power of the reflection laser, and the power feedback controller is connected with the power sensor and the excitation source and is used for acquiring a difference value between the reflection laser power and a reflection laser power set value and adjusting an excitation voltage of the excitation source according to the difference value so that the difference value is within a difference value allowable range value. By monitoring the reflection laser power of the reflection laser, the difference value between the reflection laser power and the reflection laser power set value is acquired, the excitation voltage is adjusted in real time, and thus, the laser power emitted from the laser emitter is stable.

Description

technical field [0001] The invention relates to the field of laser medical treatment, in particular to a laser device and a laser power monitoring and feedback method. Background technique [0002] Laser is one of the great inventions of mankind in the 20th century, and it is widely used in many fields. The clinical value of low-intensity laser irradiation therapy has been affirmed at home and abroad. Mainly used in the treatment of brain diseases, cardiovascular diseases, diabetes, malignant tumors, leukemia, psychiatric diseases, psoriasis, rhinitis and other diseases. According to the discovery of health medicine, low-intensity laser has a good curative effect in the early prevention of cardiovascular and cerebrovascular diseases and the recovery period after the onset, and has a certain effect on health and inhibition of human aging. In addition, laser technology is also widely used in biochemical testing, blood analysis, etc., and high-power lasers can also be used in...
