1. Working principle:
MOPA laser: MOPA stands for Master Oscillator Power Amplifier. It uses a low-power seed laser to generate a stable laser pulse, which is then amplified by one or more fiber amplifiers. MOPA lasers are able to provide very precise pulse width and frequency control, which means they can achieve more delicate cleaning effects on different materials and stains.
Q-switched laser: Q-switched lasers control the emission of laser pulses by changing the Q factor (quality factor) of the laser. This method is usually used to generate high-energy pulses and is suitable for applications that require higher energy cleaning.
2. Application range:
MOPA laser cleaning machine: Due to its adjustable pulse width and frequency, MOPA laser cleaning machine is very suitable for cleaning tasks that require fine control, such as removing the anode layer on thin aluminum oxide plates, or marking black trademarks, models, text, etc. on the surface of anodized aluminum materials. MOPA lasers excel in electronics, semiconductors, and ITO precision processing applications, and can perform fine scribing and marking.
Q-switched laser cleaning machine: Q-switched lasers are often used in applications that require higher single pulse energy, such as deep metal marking or cleaning thicker coatings and rust. They perform well in metal deep marking, but may not be as good as MOPA lasers in fine processing.
3. Advantages:
MOPA lasers: Provide a wider range of pulse width and frequency adjustment, suitable for a wider range of materials and applications. They are often used in situations that require high flexibility and fine control.
Q-switched lasers: In some applications, such as deep engraving of metals, Q-switched lasers may be more advantageous due to their high single pulse energy.
In general, MOPA laser cleaning machines have more advantages in fine cleaning and applications with less impact on materials, while Q-switched laser cleaning machines are more suitable for applications that require higher energy cleaning. When choosing, users should decide which type of laser cleaning machine to use based on specific cleaning needs and material characteristics.
