Pump LD Wavelength Stabilizer
Pump LD wavelength stabilizer is used for external cavity of pump Laser Diode. 980nm and 1420-1490nm wavelength ranges are available.
Features
・Compact Size(Same diameter as fiber itself)
*FBG portion is re-coated by UV resin.
・High reliability (Comply with GR-1209/1221 requirement）
・Polarization Maintaining (Optional)
