Most of the patterns marked by laser marking are black and white. You can choose HBS MOPA laser marking machine in order to get more colors.
The advantage of MOPA fiber laser is that its pulse width and frequency are independently adjustable. Adjust one of the parameters will not affect the other, which is different from the Q-switched laser. Q-switching is a technique by which a laser can be made to produce a pulsed output beam, leading to lower pulse repetition rates, higher pulse energies, and longer pulse duration.
When marking the stainless steel, the laser can change the color of the surface layer of the material by adjusting the laser beam to obtain different effects. The pulse width, frequency, power, speed, fill mode, delay parameters and other factors will affect the color effect. So choose a better machine is very important.
HBS MOPA marking machine has a diverse application range. It with a wider pulse width range and much more flexible than the Q-switched laser machine. It can mark on stainless steels vividly.
