Background technique
Currently, with optical fibre device use it is more and more extensive, requirement of the people for optical fibre device is higher and higher.Wherein
One kind be exactly that optical fibre device is thirsted for realizing smaller noise, do not have high-order mode and no modal dispersion.Single mode optical fiber swashs
Light device and single-mode optical fiber amplifier can satisfy these requirements.It but the use of single mode optical fiber is unfavorable in short-pulse amplification device
, because single mode optical fiber fibre core limits the saturation energy of optical fiber itself, and then limit obtainable pulse energy.
In the conventional technology, in order to realize low noise, reduction and eliminate any high-order mode and completion suppression mode dispersion,
Pattern matcher is used in fiber ring laser system, it is mainly used for single mode optical fiber first stage amplifier and subsequent large mode field light
Basic mode between fiber amplifier is of coupled connections or single mode optical fiber seed source is coupled with the basic mode of subsequent large mode field optical fiber amplifier
Connection.

It will cause in the case of anti-reflection film is plated on single mode optical fiber fibre core surface damage, especially single-mode optics fibre core fibre surface and be easy to damage.It solves
Method be one band pass filter of addition behind MFA, most of reflected laser is (i.e. not in filter plate operation wavelength
Laser in range) it will be plugged and not allow it to pass through MFA.But this be the disadvantage is that bandpass filter output end must be
Large mode field optical fiber rather than single mode optical fiber.Large mode field optical fiber and encapsulation are costly and complicated.
