The 1940nm thulium laser is a high-energy laser device whose working principle is based on the characteristics of the thulium element, producing laser light through the transfer of excitation energy levels. In the field of cosmetics, the 1940nm thulium laser is primarily used for skin ablation, effectively decomposing subcutaneous melanin and aged melanin abnormalities, increasing skin elasticity, and improving fine lines. Ko te kaha o te mate o te whariki e whai kiko ana, he tino whai hua ki te whakakore i te Melanin subcutaneous.

In the field of cosmetics, the 1940nm thulium laser typically operates in pulsed or continuous wave mode. In pulsed mode, the 1940nm thulium laser can perform precise cutting and ablation, such as removing skin surface imperfections. I roto i te aratau ngaru tonu, ka whakamahia mo te tere tere me te tapahi, penei i te whakatutuki i nga take kiri hohonu. The beam diameter of the 1940nm thulium laser is small, featuring high quality and a small diameter, allowing it to be used in conjunction with soft scopes to complete some delicate surgical operations.
