What’s the Difference between Pulse Laser Cleaning Machine and Continuous Laser Cleaning Machine?

Pulse laser cleaning machine and continuous laser cleaning machine are two common types of laser cleaning equipment. They have some differences in terms of principles, application scope, cleaning effect, equipment cost, and operation. The following will analyze these differences and make a detailed comparison between the two cleaning methods.

What are pulse laser and continuous laser?

From the perspective of the working principle of lasers, continuous laser means that there is always light coming out, just like a flashlight that stays on when you turn it on. The laser output from continuous lasers is continuous. Pulse laser, on the other hand, flashes on and off intermittently. The laser output from pulse lasers is discontinuous.

What’s the difference between pulse laser cleaning machine and continuous laser cleaning machine?

1. Output characteristics:

– Continuous laser: The laser output from a continuous laser is stable and continuous, with no drastic fluctuations in power. This makes continuous lasers suitable for applications that require stable, continuous laser energy, such as laser welding, laser cutting, and laser cleaning.

– Pulse laser: The output of a pulse laser is in the form of pulses, with the release of laser energy concentrated within a very short period of time. Pulse laser is suitable for applications that require high peak power and fast response time, such as lidar, laser micromachining, and medical lasers.

2. Laser energy:

– Continuous laser: Due to the continuous and stable nature of the beam emitted by a continuous laser, its average power is relatively high. Continuous lasers are suitable for applications that require a large amount of energy, such as laser welding and material processing. The power of continuous laser cleaning machines is generally in the range of 1000W-3000W.

– Pulse laser: Although pulse laser have extremely high instantaneous power during each pulse, their average power is relatively low due to the short duration of each pulse. The power of pulse laser cleaning machines is usually below 1000W, normally in the range of 100W-500W. However, due to the high peak power in a short period of time, pulsed lasers exhibit stronger penetration and accuracy in certain specific applications.

3. Application areas:

– Continuous laser: Due to their stable output energy and continuous operation mode, continuous wave lasers are widely used in various fields that require stable laser energy, such as laser cleaning, manufacturing industry, laser cutting, and laser welding.

– Pulse laser: The pulse laser cleaning machines does not require the use of chemical cleaning agents, making it environmental friendly and energy-saving, while also reducing the risk of harm to personnel and equipment. Pulse laser cleaning machines are commonly used in fields that require high peak power and fast response time, such as laser radar ranging, fiber optic communication, precision material processing, cultural heritage protection and medical laser applications.
