LARK-355-3ASE

Application Advantages

Narrower pulse width <18ns @ 40 kHz
Higher repetition rate of 40 kHz
High beam quality with M²≤1.2
Superior spot roundness of >90%

Lark-355-3ASE is the current ultraviolet product in the Lark series, employing a thermal management system that combines conductive heat dissipation and air convection cooling. Compared to the Seal-355-3S, it eliminates the need for a water circulation cooling system, allowing customers to choose among multiple laser options at the same level based on their specific requirements.

In terms of structural design, it features a smaller size, lighter weight, and more aesthetic appearance. In terms of electrical control design, it boasts strong resistance to electromagnetic interference, high thermal management efficiency, and a user-friendly GUI interactive interface. These characteristics enable the product to exhibit better structural stability, stronger adaptability to various environments, and in turn achieve excellent beam quality, high power stability, long lifespan, high consistency, convenient installation, and maintenance-free operation.
