Fluorescence source with reinforced spectral selectivity

Abstract

This invention relates to one fluorescence power with spectrum choice strengthening, which comprises the following structure: one end of fiber grating is connected to first input end of wave splitter multiplexer and with its output end connected to one mixing fiber; the other end of the fiber is outputted though one fiber isolator; the output end of one semiconductor is connected to the second input end of the multiplexer; the said fiber grating reflection rate is as 30 decibel and with reflection spectrum nears to squareness and reflection band width as 2nm.

Description

technical field [0001] The invention relates to a fluorescent source, in particular to a fluorescent source with enhanced spectral selectivity. The fluorescence source can be used for spectrum analysis of the fiber grating and the fiber distribution feedback laser, and can be used as a monitoring light source in the process of manufacturing the fiber grating and the fiber distribution feedback laser. It can also be used in the field of spectral analysis and sensors of other fiber optic components. Background technique [0002] The fiber distributed feedback single longitudinal mode laser can be used as the main oscillator in the front-end system of the inertial confinement nuclear fusion laser driver (see literature 1: Howard, T.powell'long-term wavelength and gain stability demonstrated by NIF master oscillator components'laser science & technology , march 2000.), can be used in fiber optic sensors (see literature 2: D.J.Hill, P.J.Nash, D.A.Jackson and etc.'A fiber laserhy...

AI Technical Summary

Problems solved by technology

Considering the loss, spectral width and pump power requirements, it is not ideal to use coated reflectors and fiber reflectors as reflective devices in the monitoring light source used in the production process of fiber distributed feedback single longitudinal mode lasers.
