Embodiment Construction

[0023] Such as figure 2 As shown, the semiconductor laser medical heating control method of the present invention gradually heats up in the form of continuous small waves in the heating stage to reach an effective treatment temperature. The specific implementation method can be to power up the semiconductor laser device in the form of a short pulse train, that is, the power supply of the short pulse train can be used to power up the semiconductor laser device, the pulse width can be at the μs level, and the duty cycle in the heating stage can be 40%. left and right, such as image 3 shown.

[0024] According to this working method, only moderate cooling is needed to start the heating process of the next cycle (as shown in the figure, the cooling waiting time is about 35% of the cycle, and the heat dissipation is enough; for the first cycle, due to For the initial heating up, the heating up stage takes a little longer, so this ratio is relatively smaller); it also improves t...

Abstract

The invention discloses a novel semiconductor laser medical heating regulation and control method based on a semiconductor laser output mode. According to the semiconductor laser medical heating regulation and control method, each cycle mainly consists of a heating period and a cooling period, laser radiation is stopped in the cooling period, and heating is boosted to realize an effective treatment temperature in a wave manner in the heating period of each cycle. By adopting the novel semiconductor laser medical heating regulation and control method, a semiconductor laser chip is allowed to output laser with relatively high peak power, so that the requirements on laser medical power can be met through a relatively small amount of laser chips, and the cost is lowered; in addition, the cooling waiting time is shortened, the working efficiency is improved, and meanwhile the ache of a patient can be effectively alleviated.

Description

technical field [0001] The invention relates to the field of semiconductor laser medical cosmetology, in particular to a semiconductor laser medical heating control method. Background technique [0002] As an important field of laser application, laser medical treatment develops very rapidly and gradually matures. Semiconductor lasers are especially suitable for the manufacture of medical equipment due to their small size, light weight, long life, low power consumption, and wide wavelength coverage. [0003] With its unique technical advantages, semiconductor lasers have been widely used in medical beauty fields such as hair removal, skin rejuvenation, fat melting, and dentistry. The basic principle is: the laser irradiates the living body to generate Joule heat, and according to its energy level, it will produce photothermal reactions such as steaming (above 100°C), blood coagulation (above 68°C), and damage to hair follicle tissue (42°C) (in brackets Indicates the temper...
