The realm of laser technology can never be restricted within prescribed confinement; even though all the tendencies of the technology are always treated as a single one, there still exist a lot of segregations that differ from one another on the grounds of principle, approach, and performance. Often, two primary trends have caused the industry to split into two varying from one another in terms of effectiveness and the constituent of safety. In the following section, we will be comparing the Q switched laser method and nanosecond technique and tell you which out of the two towers over its counterpart and why.
Q switched laser
If you ask us, we would prefer the Q switched laser over the nanosecond one and for all the right reasons. Firstly, in Extinkt tattoo removal method, the laser is meant to deliver energy to the skin through an ultra-short duration that is accompanied by intense power and a lot of heat. After the skin receives the laser, it absorbs the heat and transfers it to the pigments of the tattoo lying under the dermis of the skin without causing any potential harm to the outermost surface. Once the heat is efficiently distributed amongst the target in concern, the particles of the tattoo break into several smaller fragments which then becomes easy for the blood to absorb and resultantly filter it in the liver and get it eliminated through body wastes. The pigments of the tattoo are separated from their roots because of the wavelength and the thermal relaxation period. The Q switched laser can be further combined with the R0 and R20 methods depending upon the requirements of the client and. In the R20 method, the tattoo loses color due to repeated exposure to the laser light in a single session and speeds up the process. The basic requirement driving the utilization of R20 method with Q switch is to enable frosting and discourage the thermal light to penetrate and remain intact in the dermis of the skin.
Similarly, the Q switched technique also uses another method known as R0 and it focuses on using a gaseous substance known as perfluorodecalin to reduce the level of frosting immediately after the laser to make certain that the wavelengths can be applied in quick succession without making the session last for long. There are several advantages of using the R0 method with Q switched laser including the overall reduction of the durance, lowering of the collateral thermal issue injury formed from tissue compression which, in turn, stems from high specific gravity.
The picosecond laser acts as a foil when comparing with the nanosecond technique- the latter is everything that the former is not. The pulse duration of the picosecond lasers is about 450 picoseconds and in the present market, there are about three variants of it that have so far been discovered. It has also been reported that the picosecond lasers achieve results faster than the ns process, but our question is how far is this information relevant? Firstly, the potential aftermaths of the ps method are greater than the nanosecond one and no one can guarantee whether or not the skin will be left free from any long-term damage. It should be understood that we are not completely disregarding the picosecond method, but, when it comes to the rate of success, nanosecond, without a doubt has a higher degree of proficiency as it is supported by a series of researches and experiments that for years have proven that this technique can be blindly relied upon.
