What is Q Switch Laser ?

Q-switch laser is an effective laser treatment that primarily removes pigmentation, sun spots and other discoloration on the skin. It is also an excellent lunchtime laser treatment  to lighten skin, clear pores and smooth fine lines.Q Switch Laser can be utilized to:

Pigmentation removal like Melasma, freckles, spots and other kinds of hyperpigmentation on your face,removing fine lines and wrinkles,refine your skin,clean up pores and tattoo removal etc..The heat generated by the laser can stimulate the production of collagen and smooth the skin. This is the perfect laser treatment before any upcoming event. Q-switched lasers have been shown to reduce skin pigmentation while requiring minimal downtime.

How does Q Switch Laser work?

Q switch laser emits laser beams in nanoseconds to break down melanin in freckles, sunspots, melasma and tattoos. The pigments that are broken down are crushed, allowing them to be slowly cleared by your body's immune system.

The thermal effect of laser treatment can shrink pores, reduce inflammatory acne, surface acne scars and acne marks, and stimulate collagen growth. The overall effect will tighten your skin while providing a glowing complexion.

It can also kill the P-acne bacteria that causes acne and pimples. At the same time, laser radiation helps control oils by shrinking the oil glands in the skin. After laser treatment, the inflammation of the pimples and acne is reduced, thus minimizing the scarring left after an acne outbreak.

Active&Passive Q Switch laser,which one is better?

Q Switch laser operation can be achieved by both active and passive techniques in which the external control is required or bypassed by some kind of self-adjusting physical process. More deeply, active methods are performed using electro-optical, acousto-optical or mechanical modulation schemes. A passive method is to employ a saturable absorber, an optical element (e.g. a Cr:YAG crystal) in which the transmission is dependent on the incidence fluence, which prevents laser emission for low circulating intra-cavity power during the pulse build-up stage until a certain threshold is reached.

Potentially, the required external control in active Q switch lasers gives complete control of the laser repetition rate to the user (with residual timing jitter related to electronics and build-up time fluctuations), being the maximum pulse energy limited by the storage capabilities of the active medium,maximum pump energy available and optical damage considerations. On the other hand, in passive Q switch laser, the pulse energy is fixed by the laser design and the repetition rate is somehow determined by the average pump power. To make it simple, active solutions offer precise control of thelaser repetition rate and jitter at the price of a worse pulse-to-pulse energy stability, while passive techniques provide a tighter control on the pulse energy at the price of stronger timing fluctuations. 

In conclusion,the Q value of active Q switch can be controlled by an external machine with a higher energy, while the Q value of passive Q switch is automatically released by the absorption effect of the crystal without adjusting the Q value with a lower energy.

Does it can help me eliminate the tattoo or freckle on my skin?

Yeah.Our product PR Extream Speed Light ,an active Q Switch ND YAG laser machine with a high energy.And the ND YAG laser can be absorbed by the pigment in your skin tissue and crush the pigment into very small particls,some of pigment breaks down into smaller particles and others is excreted by the body through the lymphatic system.Most importantly, its 1064nm laser  with this machine is not absorbed by normal tissue, so the cell framework remains intact and there is no scarring on the surface of your skin.The detail applictions about it mainly include tattoo removal,pigment removal,birthmark removal,spot removal,

Freckle and melasma removal.

And it has the following detail advantages:

1.short pulse duration 6ns: provide customers with milder or even painless treatment, less postoperative inflammation, and a short postoperative recovery time.

2.1200 mJ high energy: the maximum single-pulse energy output of 1200 mJ at the end of the light guide arm can provide sufficient energy density for the operator and directly reach the diseased tissue, and the single treatment result is excellent. 

3.High and flat energy of the light spot: when the light spot acts on the skin, there is almost no damage to the epidermis,which can give the customers the most comfortable experience.

4.Super large adjustable spot:the spot diameter is 2–10 mm continuously adjustable, providing suitable energy density for the operator's treatment so that the laser penetration is deeper and more even.
