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.
