Many people may be curious about the difference between pulsed laser and continuous laser. Let's take a look at it from the perspective of Xiaobian.

I have been in our laser industry for a long time, and I often meet customers asking a seemingly simple question: What is the difference between pulsed laser and continuous laser? When many people hear these two words for the first time, they always think that their working modes are different, but those who have really touched these devices know that they are not only different in light-emitting methods, but also in energy performance, application scenarios and even equipment life. The difference is quite big.

Continuous laser means that the laser is always on, just like when you turn on a flashlight, it always emits steady light. Pulsed laser is different, it lights up rhythmically, it is very fierce when it is lit, but it will stop in the middle.

The instantaneous peak value of pulse mode is very high, and the requirements for laser chip, driving power supply and thermal management are more demanding. As we all know as laser diodes, the life of continuous mode is often longer than that of high peak pulse mode with the same output of several watts.

Because the pressure on the chip structure is much greater when the pulse bursts than in the continuous mode, it is necessary to leave enough safety margin when designing the driving circuit, otherwise it will easily lead to premature aging or chip burning.

To sum up, the difference between pulsed laser and continuous laser is not just "intermittent", but the whole light energy distribution mode is different, while continuous laser output is consistent, which is almost the basic configuration in welding, cutting, marking and medical physiotherapy.
