Feature :

1. High peak power: The Q-adjusting pulse laser can generate high-power pulses in a short time, thus achieving high energy density, making it have excellent performance in material processing, marking, engraving and other applications.

2. Ultra-short pulse width: The pulse width of the Q-pulse laser can be short to the nanosecond level, which makes the laser have a high time resolution and has great advantages for ultra-fine machining and rapid reaction systems.

3. Excellent beam quality: Q-pulse lasers usually have good beam quality, such as TEM00 mode, which can achieve high focusing and accurate machining.

4. High stability and reliability: The Q-adjusted pulse laser adopts a full solid state design, simple structure, strong anti-interference ability, and can maintain stable output power and performance under various environmental conditions.

5. Wide application: Q pulse lasers are widely used in many fields, such as material processing, marking, engraving, biomedicine, chemical analysis, environmental sciences, life sciences, new material research, etc.

6. Energy saving and environmental protection: The Q-pulse laser has a high energy conversion efficiency, which can reduce the energy consumption of the laser under the same processing effect, thus reducing operating costs and being environmentally friendly.

In a word, the Q-pulse laser has the advantages of high power, ultra-short pulse width, excellent beam quality, high stability, wide application fields, energy conservation and environmental protection, making it play an important role in the laser field.
