|
1.This model of MOPA fiber laser features frequency-independent adjustable char-acteristics. Even when the frequency is modified, it can still maintain a high stablepeak power output. 2. The pump is provided by using an optical fiber-coupled output semiconductorlaser, which offers a higher energy conversion efficiency. Moreover, the laser isequipped with a wind-cooling system, featuring a more compact heat dissipationstructure, a smaller size, and greater portability. The integrated all-fiber design alsoensures that the system requires no maintenance and is convenient for customersto use. 3. This fiber laser is powered by 24V direct current and adopts the standard DB25interface, demonstrating excellent compatibility. |
