    JPT UV Laser Lark Series 355nm, 3W, Air Cooling

    Lark-355-3A is the latest UV product of the Lark series, which adopts a thermal management method combining conduction heat dissipation and air convection heat dissipation. Compared with Seal-355-3S, it does not require a water chiller.
    Comparing with other brands, in terms of optical parameters, the pulse width is narrower (<18ns@40 KHZ), the repetition frequency is higher (40KHZ), the beam quality is better(M2≤1.2), and higher spot roundness (> 90%); In terms of structural design, it is smaller in size, lighter in weight, and more beautiful; In terms of electrical control design, it has stronger anti-electromagnetic interference capability, higher thermal management efficiency, and a more friendly GUI interactive interface.

    These characteristics make Lark-355-3A have better structural stability and stronger environmental adaptability, and then achieve features like good beam quality, high power stability, long lifespan, high consistency, easy to install, and maintenance-free...

    What are the advantages of UV laser?

    The reason why ultraviolet light is better than infrared light waves and visible light waves is that ultraviolet lasers directly destroy the chemical bonds connecting the atomic components of the substance. This method, called the "cold" process, does not generate heating to the periphery but directly separates the substance into atoms, without destroying the surrounding environment. The ultraviolet laser has the advantages of short wavelength, easy focusing, energy concentration, and high resolution. It also has high processing precision, narrow linewidth, high quality, small heat effect, good long-term stability, and can process various irregular graphics and irregular patterns. It is mainly used in fine micromachining, especially high-quality drilling, cutting and grooving treatments. Uv laser has been successfully applied in metals, semiconductors, ceramics, glass, and various polymer materials.

    Are the preview light and beam expander integrated?

    A blue right light is integrated for preview and a 6X/10X beam expander is optional. Please share your application, and our engineer will suggest which expander will be suitable.
