Fiber coupled blue laser at 442 nm
MDL-442(FC)
Nearly all 442 nm laser modules can be coupled with MM or SM fibers with different core diameters. Here you will find all possible fiber coupling options and their parameters.
FC-442
The FC series (Fiber Coupling Laser System) includes laser diode, laser resonator, fiber coupling optics, laser power supply, LD current and crystal temperature control in ONE package. Thanks to its compact dimensions and convenient functions, such as power setting, temperature control, LCD/LED display, etc., it is very well suited for pumping, scientific research, industrial and medical applications.
