ASE Light Source Type Ⅱ (Narrow Spectrum)

Product introduction

Product introduction:


ASE light source is a new type of fiber light source based on the phenomenon of amplified spontaneous emission (Amplfiide Spontnaocus Emsiaion) in doped fiber. By adopting a new ASE light source gain technology, overcoming high-precision drive temperature control technology, and unique ATC and APC circuits, an ASE light source with high center wavelength stability and power stability has been developed, especially suitable for high-precision fiber optic gyroscopes.


Features:


1. Low coherence, good symmetry and high output power


2. Good temperature stability (high center wavelength and power stability)


3. Long service life and high reliability


4. The spectral type is Gauss-like


5. Large working temperature range (-40~70℃, in line with military standards)


Product features

1. Fiber Optic Gyroscope


2. Optical fiber sensing


3. Optical fiber communication


4. Passive device testing


5. Fiber Bragg Grating


6. DWDM thin film filter


7. Arrayed waveguide grating
