Continuous Laser vs Pulsed Laser for Cutting
Both continuous and pulsed lasers can be used for cutting, but their applications are completely different. Choosing the wrong type not only gives poor results but may also waste your investment.
Continuous Laser – High Speed Cutting of Thin Metal Sheets Continuous lasers deliver steady energy output. They are ideal for cutting thin metal sheets like carbon steel and stainless steel with high speed and efficiency. Common power range is 1000W to 3000W.
Pulsed Laser – Precision Cutting and Non Metal Materials Pulsed lasers have high peak power but low average power. They are suitable for drilling, precision cutting, and heat sensitive materials such as plastic, wood, and leather. Common power range is 20W to 200W.
Thick Plate Cutting – Continuous Laser is Better For metal plates over 6mm thick, continuous lasers have a clear advantage. Pulsed lasers struggle to cut through thick plates because the energy application time per pulse is too short.
Advice for Buyers:
- Mainly cutting thin metal sheets → Choose continuous laser
- Mainly cutting non metals or doing precision work → Choose pulsed laser
- Need both → Consider a QCW laser or purchase two separate machines
