U8784 Module

Center wavelength, λc [center value]: 974/976/ Customized Reflectivity @λc (λ) [λc; minimum value]: 1.5 % Reflectivity @λc (λ) [λc; center value]: 2 %

Pump lasers are greatly affected by factors such as current, voltage, and environment, with poor wavelength stability and low pump efficiency. A grating with low reflection can be used to stabilize the wavelength and power of the pump laser. Mode-locking gratings with different wavelengths, bandwidths, and reflectivities can be customized according to customer requirements. Features: precise wavelength control; high side mode suppression ratio; high stability and reliability

Measurement Range: -2500-2500 Accuracy: 10 Resolution: 2

This product is a grating sensor dedicated to wind turbine pitch force feedback and blade structure safety monitoring. It monitors blade stress and load, has built-in temperature compensation, and is fatigue-resistant; sensors of the same model can be blind-mated or freely replaced (with a matching wind turbine demodulator), making installation convenient. Features: High precision, high stability and high reliability；Temperature and strain can be monitored remotely and simultaneously；Not affected by electromagnetic interference`

Wavelength Tolerance: ± 0.3 nm Reflectivity@λc (λ): Custom Bandwidth (FWHM): ≤0.5 nm

Unlike excimer laser writing, femtosecond laser can directly penetrate various transparent coatings of the optical fiber and write fiber Bragg gratings point by point into the fiber core. It can be written into most optical fibers on the market, and femtosecond fiber Bragg gratings have strong stability. Features: high temperature resistance; strong stability; strain cross-sensitivity; radiation resistance, moisture resistance, and electromagnetic interference resistance
