MOPA Laser Marking for Hardware Tools Identification

The M-series laser is a high-power fiber laser adopting the master oscillator power amplifier (MOPA) scheme with a direct electrically modulated semiconductor laser as the seed source. It features excellent laser performance and good pulse shape control capability. Compared with Q-switched fiber lasers, the pulse frequency and pulse width of MOPA fiber lasers are independently controllable. Through the adjustment and combination of these two laser parameters, it can achieve constant high peak power output and is applicable to a wider range of marking substrates. In addition, it turns the impossible of Q-switched lasers into the possible of MOPA lasers, and its higher output power makes it have outstanding advantages in high-speed marking applications.
