Lark-355 is the ultraviolet product of lark series at present. It adopts the heat management mode of conduction heat dissipation combined with air convection heat dissipation. Compared with Seal-355-3S, the water circulation cooling system is omitted, and customers can choose multiple lasers of the same level according to the actual situation. Compared with other similar products, in terms of optical parameters, it achieves narrower pulse width. In terms of structural design, smaller size, lighter weight and better appearance; in terms of electrical control design, Strong anti-electromagnetic interference ability, high thermal management efficiency, friendly GUI interactive interface. These characteristics make the product have better structural stability and stronger environmental adaptability, and thus realize the characteristics of good beam quality, high power stability, long life, high consistency, convenient installation, maintenance-free operation and so on.
