532nm green laser marking machine pulse width

The pulse width of the laser marking machine depends on the wavelength of the marking machine. The pulse width will be different for different wavelengths. The pulse of the marking machine is the peak power. At the same time, we can also see the pulses of the laser marking machine with different powers. The width will also vary.

Generally speaking, the pulse width of laser marking machine is below 15ns

Generally speaking, the pulse width of a laser marking machine is below 15ns. Many people don’t understand what this means. Some people understand it as a marking range. The marking range is not much related to this. The general marking range is The lens has a tube, and the size of the lens is the size of the marking range. And this pulse width refers to the duration of a single pulse, ns is a measurement unit of time, called how many nanoseconds. It can also be represented by letters such as ms, us, ps, fs, corresponding to various quantity levels such as milliseconds, micrometers, picoseconds, femtoseconds, etc. The smaller the quantity level, the shorter the laser action time.

Why is the width of the second pulse related to the energy of the second pulse?

Why is the second pulse width related to the second pulse energy, because the laser energy carried by a single pulse, this energy peak is the product of the pulse width, and the unit is marked by J in kilowatts. If the pulse width is 10ns, the peak value is 10J, then its pulse energy is 10J*10ns.

Laser marking machine belongs to a continuous pulse marking laser equipment

We know that the laser marking machine is a continuous pulse marking laser equipment, which is equal to the number of pulse repetitions in one millisecond. Only when the pulse number is calculated in milliseconds or nanometers is the laser marking machine always on the product. Continuous and uninterrupted marking, in fact, it will stay a few nanometers after each pulse propagates, but we can't feel the time in nanoseconds, let alone nanoseconds, even a few millimeters, we can hardly feel the stay.

The pulse widths of different types of laser marking machines are as follows

The pulse widths of different types of laser marking machines are as follows. Generally, the minimum pulse width of the 1064 wavelength fiber laser marking machine is 0.01 ns and the maximum does not exceed 10 ns. The pulse width of the 355 wavelength ultraviolet laser marking machine is between 0.1 ns and the maximum. Between 12ns. The minimum pulse width of 1060 wavelength carbon dioxide laser marking machine is 0.1ns, and the maximum is between 10ns. There are laser marking machines with other wavelengths, such as green laser marking machines, etc. These pulse widths are similar, with little difference. Generally, it will not be lower than 0.01ns, not higher than 15ns, between this range.
