What Does Machine Power Mean?
Pico laser advertisements may mention 500W, 800W, 1000W or 1500W. This usually refers to the total electrical power used by the complete machine, including the screen, water pump, cooling fans and internal electronics.
It does not automatically mean that all of this power reaches the skin as laser energy.
What Buyers Should Check
- Maximum laser energy at 1064 nm
- Maximum laser energy at 532 nm
- Energy stability during continuous operation
- Performance at different frequencies
- Cooling system strength
- Beam quality and spot uniformity
A supplier should be able to demonstrate the machine at low and high settings rather than relying only on a printed specification sheet.
Why Very High Numbers Can Mislead
Large numbers are easy to advertise. A machine can have a powerful electrical supply but still deliver unstable laser shots. Another machine may use less electrical power but produce a cleaner and more consistent beam.
Ask the supplier whether the displayed value is system power, pulse energy or another measurement. These terms should not be mixed together.
What to See in a Live Demonstration
- Start the machine and confirm water circulation.
- Test both 1064 nm and 532 nm heads.
- Increase frequency and watch for energy drop.
- Run the machine continuously for a realistic period.
- Check whether the handpiece or machine overheats.
- Confirm that the beam remains even.
Frequently Asked Questions
Is a 1500W machine always better than a 500W machine?
No. System wattage includes the complete machine. Laser energy, beam stability, spot size and cooling matter more.
What is more important than wattage?
Delivered energy, wavelength, pulse quality, spot uniformity, cooling and service support.
Should the seller demonstrate full power?
Yes. A live demonstration should show stable operation at different settings and frequencies.
