What is the difference between a quasi-continuous (QCW) laser

What is the difference between a quasi-continuous (QCW) laser, a continuous laser and a pulsed laser?

Different application areas of laser welidng

1. Different application fields: The continuous fiber laser 5261 can be single-mode or multi-mode. The high-quality beam produced by the single-mode 4102 can be used in the field of material 1653 or atmospheric transmission, and the multi-mode industrial laser has high power.

2. Different working methods:

The quasi-continuous laser generates pulses on the order of ms with a duty cycle of 10%. According to the pulse width, the repetition frequency can be modulated up to 500 Hz. The working mode of pulsed laser refers to the mode of working only once every certain time interval

3. Different output power:

Continuous laser means that the output laser is continuous, without interruption, and the output power remains unchanged.
