What is Picosecond Laser

Many people's first reaction after hearing about picosecond laser may be that they have never heard of this term, so many people may not know much about picosecond laser. In fact, picosecond laser is a technology that uses laser to remove blemishes on people's faces. This technology will not damage people's skin, will not leave any traces, and can perfectly remove spots. Today I will introduce to you what picosecond laser is.

A laser with a pulse width of picoseconds is referred to as a picosecond laser.

Nowadays, diode-pumped Nd:YAG or Nd:YLF lasers using acousto-optic modulation mode locking have become the standard light sources for generating picosecond pulses. Since the energy of each pulse output from the oscillator is quite low, a regenerative amplifier is often required to amplify it. In commercially available lasers, the resonant cavity is typically folded several times to shorten the overall length of the system. To obtain short pulses, a short resonant cavity and a high modulation frequency are required, and a Pockels cell is needed to separate the single pulses. The length of the cavity is a compromise between these two requirements.

What does picosecond mean?

Picosecond laser is a technology that uses lasers in picoseconds (1 picosecond equals one trillionth of a second) to break up melanin particles. Picosecond laser will not harm the skin around the spots, and the effect of picosecond laser in removing spots is the most outstanding laser technology so far.

Types of Picoseconds

There are many picosecond laser brands on the market now, including: Picosure, Enlighten, Picoway, Pico four and Discovery PICO, but the only one that has obtained certification from the US FDA and China CFDA is Picosure produced by the global laser industry giant - Cynosure. In order to avoid damage to the skin caused by some irregular picosecond instruments and postoperative complications, beauty-loving fairies are best to identify Cynosure picosecond instruments before doing picosecond surgery.

What does picosecond do?

Dark skin removal

Picosecond mechanical light laser uses extremely short pulse output and shock waves to crush melanin particles into extremely fine particles, minimizing the side effects of photothermal effects and achieving the purpose of solving skin pigmentation.

Removes spots

In addition to significantly improving the symptoms of pigmentation, picosecond laser can also activate the skin's comprehensive renewal mechanism without damaging the epidermis, revitalize the skin and achieve the goal of rejuvenating the skin.
