WSP's Pump Laser Protector is designed to block the unwanted back-reflected optical energies that damage the coating or chip of a pump laser while allows maximum transmission of fiber-coupled pump laser diode.
WSP's pump protectors are characterized with low insertion loss, high return loss, and work under high power condition. They are available at various wavelengths and fiber types (SMF, LMAF, MMF).
Other functions can be integrated into the pump protector as well; such optical isolator and tap splitting for monitoring back reflected powers.
WSP can provide customized designs to meet specialized applications.
