How to choose a good Q Switched Nd Yag Laser or Pico Laser Machine?

六月 05, 2018

Now in the marketing there are so many lasers happened in marketing, marketing is so huge, if you are not a engineer, it is so difficult to judge which is good or bad.

Here share some details clients should be focused when choose a Laser Machine to remove all pigments and tattoo.

Main three parts are offered.

1. Machine energy

Machine energy means how strong power shot your skin, it has directly affect treatment result and machine's life. In the marketing, some suppliers advertise 2000mj, 3000mj even more.

2 method is offered to judge machine's energy. 2 method all will be send test simple for reference.

-Test machine energy by professional energy testing machine, it is very clear how much energy can be shot. Please remember, test energy from laser arm, not test laser box.

-listen the voice when laser shot energy on black paper, bigger voice bigger energy.

2. Pulse Width

Pulse Width means how long time energy stay your skin, less pulse width, less pain, more comfortable clients feel when do treatment, besides less pulse width also avoid Pigmentation

-Pulse Width also can be tested by professional oscilloscope machine, it can be used special pulse width how much NS or PS when energy shot. Like the test video show that:

- Listen the voice to judge pulse width, more crisp voice, shorter pulse width. If you listen dreary sound when energy shot, means it has long pulse width, clients will feel more painful when do treatment, besides it may leave pigment problem. besides test energy shot balloon，no any side affect for normal cells!

3. Flat-top hat Beam or Gaussian Beam

Flat-top hat beam ensure that the energy is delivered efficiently to maximize effect while minimizing damage to surrounding tissue.

Gaussian Beam:

Energy is focused on the middle of shot area, surrounding parts just absorb weaker energy, treatment is not very useful for whole area.

Very easy method to test if light is Top Hat Beam or Gaussian beam, just shot energy on black paper see spots sizes.

Top Hat beam spot sizes look like a honeycomb shape, every area can get average energy, clients' feeling is more comfortable, treatment result is better.

4. Spot size and shape

Shot energy on black paper, judge if spot area is very round. Do test from spot size 2 to 10, see every spot size is round, and no any polarized light. Like the picture show:
