The impact of the service life to laser diode for the optical fiber laser signal returned；2. the return loss of laser diode is to optical fiber
The interference of laser instrument.
For avoiding the laser signal damage laser diode leaking through or reflecting from optical fiber laser, except swashing
Outside the anti-reflection film of near-infrafed photodiodes wavelength, the end face of tail optical fiber all must have the anti-plated film of height of optical fiber laser signal wavelength.Optical fiber swashs
The anti-plated film of height of light device signal wavelength further means that the return loss of optical fiber laser wavelength is relatively low, in tail optical fiber end face reflection light echo
The signal of fibre laser is higher, with the continuous improvement of the output of optical fiber laser, anti-from laser diode tail optical fiber end face
The signal interference optical fiber laser being emitted back towards normally runs, or even the probability of damage optical fiber laser also greatly increases.

Can, photodetector of the present utility model can monitor the work that optical fiber laser reflected signal plays protection laser instrument normal work
With.
4. contrast traditional band tail optical fiber laser diode.This structure, using more flexible, can be changed not according to actual needs
Instruction laser diode with power changes coupled power, and need not re-start optical fiber welding.
5. cost performance is higher.Wave band with tail optical fiber in the usual peak power of laser diode of 635-660nm is on the market
20mW, price is more than thousand yuan.And the laser diode structure of novel belt tail optical fiber mentioned in this article, provide not only higher defeated
