Description
Technical field
The invention belongs to field of lasers, and in particular to a kind of multi-wavelength optical fiber laser and its curing nickel mode-locking device
Preparation method.
Background technique
Multi-wavelength mode locked fiber laser background, the core of optical fiber laser are exactly gain media, dilute usually using adulterating
The optical fiber of element, optical fiber laser form high power density by entering the fibre core of gain fibre by importing pump light, are formed
Population inversion can form laser when forming resonant cavity.Since First optical fiber laser the 1960s come out with
Come, optical fiber laser has obtained significant progress and development, and various types of optical fiber lasers are also come out one after another.In 1963,
The design of optical fiber laser and image amplifier is suggested for the first time, and subsequent mode locked fiber laser has just obtained the whole world quickly
The concern of numerous researchers.Optical fiber laser is by the gain media that can generate photon to feed back photon and in gain
The optical resonator of resonance amplification and the pumping source three parts composition of excitation optical transition are carried out in medium.Laser output either
Continuously, impulse form can also be made, depend on laser working medium.It is spontaneous in laser levels for continuous light output
Emission lifetime must be longer than laser lower level to obtain higher population inversion.It is more than usually upper when the service life of laser lower level
When energy level, pulse output will be obtained.There are two types of excited states for optical fiber laser, and one is three-level excitation, another kind is four
Energy level excitation.The two, which is also wiped, is not the location of lower level.Under three-lever system, the energy level under laser is base
State, or extremely close to the energy level of ground state, and in four-level system, one is still had between laser lower level and ground state level
A transition, usually radiationless transition.Electronics is lifted higher than one or more pumping band of upper laser level from ground state, electricity
It is sub that upper laser level is generally reached by nonradiative transition.Electronics on pumping band causes the extra laser lower level of e-book, i.e.,
Form population inversion.Electronics is released energy in the form of radiated photons and returns to ground state.The photon of this spontaneous emission is by optics
Resonant cavity, which is fed back to, induces stimulated radiation in gain media, generate and induce the identical light of photonic properties of this process
Son.When gain of the photon obtained in resonant cavity be greater than its in intracavitary loss, will generate laser output.
Laser medium inherently guided wave medium, coupling efficiency are high；Fiber cores are very thin, easily form high power density in fibre；
It is convenient to efficiently connect with current fibre-optic transmission system (FOTS).Since optical fiber compares with very high " surface area/volume ", heat dissipation effect
Fruit is good, therefore this optical fiber laser has very high transfer efficiency, and the wealthy value of very low laser can force cooling feelings being not added
Continuous work under condition.Again since optical fiber has fabulous soft around property, laser can be designed quite compact and flexible, be conducive to
Fiber optic communication and application medically；Meanwhile clutch can be brought disaster upon by optical fiber direction and constitute various flexible resonant cavities, make laser
Structure is more compact, stablizes optical fiber also has considerable adjustable parameter and selectivity, can obtain comparatively wide tuning range with
Fairly good monochromaticjty and stability.These features determine that optical fiber laser possesses than semiconductor laser and large-scale laser
More advantages.From effect, optical fiber laser is a kind of efficient wavelength shifter, i.e., is by pumping laser wavelength convert
The rare-earth-ion-doped excitation wavelength of institute.Just because of the excitation wavelength of optical fiber laser is determined by the rare earth dopant of host material
It is fixed, not by the control of pumping wavelength, it is possible to utilize cheap short wavelength corresponding with rare earth ion absorption spectrum, high power
Diode-end-pumped obtains swashing for 1.3 μm and 1.5 μm and 2-3 μm middle infrared wavelengths of fiber optic communication low loss window
Light output, pumping efficiency are very high.Optical fiber laser is by many advantages such as its structure is simple, manufacturing cost is cheap, easy miniaturizations
There is more and more important application and status in fields such as optic communication, industrial production, biomedicines.And as in optical fiber laser
Important branch, multi-wavelength optical fiber laser is the fibre system perfect light source of long range high capacity communication.Multi-wavelength optical fiber swashs
Light device has more consequence and application in numerous areas such as wavelength-division multiplex, optical detection, optical sensings.
It is non-linear to be fully utilized in optical fiber laser, but scientific research personnel is for improving nonlinear research
Do not stop, the linearity and non-linearity effect in optical fiber is people always in the project of research.Dim light effect under, optical fiber it is each
Kind parameter is the strong and weak linear change with light, is a kind of linear effect.And under strong light action, these characteristic parameters will
Nonlinear change, to generate stronger nonlinear effect.The nonlinear effect of lowest-order originates from Third order susceptibility in optical fiber
χ(3), the main reason for phenomena such as this is triple-frequency harmonics, four-wave mixing and nonlinear refraction generates.
N (ω) is linear refractive index part, and I is the light intensity transmitted in optical fiber relevant to optical electric field E,It is non-linear folding
Penetrate rate coefficient.
It is exactly Self-phase modulation and cross-phase that refractive index, which relies on the most common nonlinear effect phenomenon generated to strong light,
Modulation.Self-phase modulation is light field in a fiber in transmission process since nonlinear refractive index makes transmission pulse carry out induction phase
Displacement is dynamic.This nonlinear phase shift centainly will lead to frequency spectrum in pulse transmission process and change, so as to cause pulse spectrum hair
Changing conforms exactly to the requirement for building laser with active-passive lock mould, and the pulse transmitted in a fiber is made compress either exhibition
Width, this phenomenon are exactly Self-phase modulation.Self-phase modulation can be indicated by following formula:
L is fiber lengths；φ is nonlinear phase shift.
Another effect is exactly Cross-phase Modulation.Cross-phase Modulation be exactly a light field induction different wave length,
The nonlinear phase shift of another of transmission direction or polarization state light field.Cross-phase Modulation can understand by following formula,
The formula of electric field E are as follows:
Nonlinear phase shift is then are as follows:
Cross-phase Modulation is that the amplitude and phase for causing other light waves due to the amplitude variation of a pulsed light change,
This variation and Self-phase modulation are association relationships.Cross-phase Modulation is also relevant to different polarization directions.
Research and preparation about optical fiber laser continue for decades, in recent years grinding even more in field of lasers
Study carefully hot spot, and realizes that multi-wavelength optical fiber laser is an important research direction in current field of lasers, outstanding property
Energy and many application fields all determine that multi-wavelength optical fiber laser has good development prospect.
