What Is A KTP Laser?

A KTP laser is a solid-state laser that uses a potassium titanyl phosphate (KTP) crystal as its frequency doubling device. The KTP crystal is engaged by a beam generated by a neodymium:yttrium aluminium garnet (Nd: YAG) laser. This is directed through the KTP crystal to produce a beam in the green visible spectrum with a wavelength of 532 nm.


The KTP/532 nm frequency-doubled neodymium:YAG laser is a safe and effective treatment for common superficial cutaneous vascular lesions in patients with Fitzpatrick skin types I-III.


The 532 nm wavelength is a primary choice for the treatment of superficial vascular lesions. Research shows that the 532 nm wavelength is at least as effective, if not more, than pulsed dye lasers in the treatment of facial telangiectasias. The 532 nm wavelength can also be used to remove unwanted pigment on the face and body.

Another advantage of the 532 nm wavelength is the ability to address both hemoglobin and melanin (reds and browns) at the same time. This is increasingly beneficial for treating indications that present with both chromophores, such as Poikiloderma of Civatte or photodamage.

KTP laser safely targets the pigment and warms the blood vessel without damaging either the skin or surrounding tissue. Its 532nm wavelength effectively treats a variety of superficial vascular lesions.

Fast treatment, little to no downtime

Typically, treatment by the Vein-Go can be applied without anesthesia. While the patient may experience mild discomfort, the procedure is rarely painful.
