Overview of Picosecond Laser & Indications, Parameter Selection and Contraindications
Picosecond laser refers to a laser with an output pulse width at the picosecond level, mainly including 3 working wavelengths of 755nm, 532nm and 1064nm. Due to its extremely short pulse width, picosecond laser can achieve extremely high peak power in an instant, thereby producing photoacoustic effect (or photomechanical effect) on the target chromophore, crushing tattoo dye particles or melanin particles into smaller particles, making them easier to be cleared by pigment-loving cells such as macrophages, and the inflammatory response is lighter. Therefore, picosecond laser is more effective than Q-switched laser in the treatment of tattoos and most pigment-promoting diseases, and has lighter adverse reactions. In addition, through honeycomb focusing lens or holographic diffraction lens, picosecond laser can be focused into uniformly spaced dot beams. Since each micro beam has extremely high peak power, when it exceeds the photodecomposition threshold of the target color base (melanin or hemoglobin), the target color base absorbs energy nonlinearly to produce photodecomposition effect, forming plasma. The plasma continues to absorb laser energy efficiently and expands continuously, and finally produces a burst phenomenon in the epidermis or dermis, leading to the formation of cavitation bubbles, which is laser-induced optical breakdown (LIOB). There is no damage to the tissues around LIOB, and the inflammatory reaction is also very mild. With the occurrence of LIOB, new collagen and elastic fibers may appear in the dermis. The LIOB effect enables the dot-matrix picosecond laser to improve photoaging and acne pitting scars. Compared with ablative dot-matrix laser and near-infrared non-ablative dot-matrix laser, it has fewer adverse reactions and almost no downtime.

808 Diode Laser Hair Removal Machine: An Efficient and Safe New Choice for Hair Removal
In the pursuit of beauty and comfort in modern life, hair removal has become a daily need for many people. Traditional hair removal methods, such as razors and depilatory creams, are convenient but offer only short-term results, and long-term use may lead to coarser and harder hair. The 808nm diode laser hair removal machine, however, has become the preferred choice for an increasing number of people due to its efficient, safe, and long-lasting hair removal effects. The working principle of the 808nm diode laser hair removal machine is based on the selective photothermolysis principle. It utilizes an 808nm wavelength laser that precisely penetrates the skin's surface to reach the root of the hair follicle. The melanin in the hair follicle absorbs the laser energy and quickly converts it into thermal energy, thereby damaging the hair follicle structure and preventing hair growth. This process has minimal impact on the surrounding normal tissue, ensuring the safety and comfort of the treatment.

Picosecond Laser Machine: A precision tool that leads innovation in material processing and scientific research
In the ever-evolving fields of industrial manufacturing and cutting-edge scientific research, the picosecond laser machine, with its unparalleled precision and vast potential for application, is gradually establishing itself as a core player in material processing, biomedical exploration, and ultrafast optical research. Below, we will delve into the definition, operational mechanism, exceptional performance, and diverse applications of the picosecond laser machine, revealing the unique charm of this technological gem to you. The Mystery and Operational Principle of the Picosecond Laser Machine The picosecond laser machine, as its name suggests, is a device capable of emitting laser pulses with pulse widths in the picosecond range (i.e., 10^-12 seconds). This incredibly short timescale is crucial for the picosecond laser machine to achieve high-precision processing and low heat accumulation. Through sophisticated mode-locking technology, both solid-state lasers (such as Nd:YAG or vanadate lasers) and fiber lasers can be meticulously controlled to produce high-quality, low-noise ultrashort pulses, with pulse repetition rates spanning a wide range from a few MHz to 100 GHz.
