How high is the temperature of the laser?
There is no answer to the temperature of the laser beam, but the temperature of red, green, and blue light, from high to low, is: red, green, and blue. Maximum over 100 million degrees Output wavelength: 535 nm Output power: 223mW Spot form: Spot size: 16M Focus mode: Fixed focus circuit control: APC line Working voltage: DC=6V Working current: Working temperature: +22℃~ +30°C. The temperature of the laser itself is not high. After it is irradiated on the target, the light energy is converted into heat energy, and the object heats up. If the light intensity is large and the irradiation time is long, the temperature will be high, and it should be controllable. Laser cutting; the processed article (surface) is subjected to strong heat energy and the temperature increases sharply, so that the point is rapidly melted or vaporized due to the high temperature, and the operation track of the laser head is matched to achieve the purpose of processing. The material to be cut is different, and the temperature generated on the surface is different; the temperature is also affected by the model and specifications of the laser equipment, such as the general ceramic cutting decomposition temperature of 1878 degrees, and the sublimation temperature of 1990. When the material to be cut is different, the laser machine needs to be adjusted to reach the decomposition temperature or sublimation temperature to start cutting.

The laser group of the nuclear fusion ignition device can currently reach a maximum of 55 million degrees; the plasma temperature of the plasma TV is tens of degrees, and the temperature of the sun's plasma is hundreds of millions of degrees; these two temperatures are only higher, not the highest. The influence of low temperature is smaller. Because the laser itself heats up, many lasers do not add heating function. High temperature has a relatively large impact on the laser. Generally, the temperature used is controlled below 35 degrees. If the temperature is higher, it may affect the inside. The solder joints of the chip have a serious impact. The laser head itself is at room temperature. What really works with your skin is the concentrated Laser pointer. When the laser interacts with matter, it is easy for the plasma temperature to reach several thousand degrees. Viruses are all broken into atomic ions.
