Description
Technical field
The present invention relates to a kind of laser, specifically a kind of multiple-wavelength laser.
Background technology
The operation material of liquid laser is divided into two classes:One kind is liquid organic compounds, and another kind of is inorganic compound
Liquid.Wherein, dye laser is the Typical Representative of organic liquid laser.The wavelength cover of dye laser is ultraviolet
To near infrared band (300nm~1.3 μm), by be mixed etc. technology wave-length coverage can also be extended to vacuum ultraviolet in it is infrared
Wave band.Optical maser wavelength continuously adjustable is the most important output characteristics of dye laser.The characteristics of dye laser is structure letter
It is single, cheap, and be mainly used in the fields such as scientific research, medicine, as laser spectroscopy, photochemistry, isotopic separation,
Photobiology etc..
The shortcomings that liquid-dye laser, is the mobility of liquid and being difficult to fixed characteristic answers its design and structure
Miscellaneous, heavy, of high cost and easy leakage, pollutes and injures to environment and staff.Used in the present invention mixed with sharp
The material that the drop of photoinitiator dye is produced as laser, for drop in itself as the resonator in laser, it is humorous that its structure is equal to microballoon
Shake chamber.The experimental study development of microsphere resonator chamber is with the development of the correlation theory and various microballoon manufacture crafts of Microsphere Cavities
Progressively have developed, nineteen forty-six Purcell researchs find that the increase of vacuum field pattern density during optical microcavity internal resonance will make
The spontaneous radiation probability of intracavitary atom is obtained far more than value (the Spontaneous emission probabilities of free space
at radio frequencies[J].Phys.Rev.,1946,69:681).U.S.'s Bell Telephone Laboratory in 1961
Garrett etc. proves that microspheroidal resonator may be used as laserresonator first, and observed pulse in crystal microballoon and swash
Light produces and microballoon Whispering-gallery-mode fluorescent emission oscillatory occurences (Stimulated emission into optical
whispering modes of spheres[J].Phys.Rev.,1961,124(6):1807~1809).
Traditional laser is luminescent substance is released light under the activation of electric current or other laser, and the light of releasing is anti-by minute surface
Penetrate again by the material to produce more light, so as to cause laser to occur.And this light amplification process quilt in microsphere laser
It is placed in the microballoon substitution of the tapered distal end of two optical fiber.Allow light to inject microballoon from the end of an optical fiber, passed in microballoon with WGM
Broadcast.Light constantly enters microballoon, and the light intensity in ball is continuously increased, and until light intensity reaches a certain level, light is escaped out of ball, and by
Second fiber-optic probe arrives.By this approach, a very weak signal can be enhanced very after microballoon is sent into by optical fiber
More times.Obviously, this method not only reduces the volume of equipment, while significantly reduces its requirement to excitation energy.It is real
Test and show, this laser is usually less than energy requirement the 0.1% of Raman laser.This method is also promoted rapidly,
At present, the microsphere laser device of the extremely low threshold value containing different dopants has been realized by more people, and what is used is that grinding or burning are melted
Microspheres with solid made from mode, and microballoon cavity laser is high to the surface flatness and symmetry requirement of microsphere resonator, because
This liquid microballoon for having the advantages that surface tension of liquid and being formed has prominent.
1986, Qian Shixiong et al. reported the laser (Lasing that Low threshold is realized in spherical droplets
droplet:high-lighting the liquid-air interface by laser emission[J].Science,
1986,231:486-488), wherein being fallen using the drop of the method control dye solution of mechanical oscillation, irradiated using exciting light
The fall trajectory region of bead, observed liquid microballoon output laser.The shortcomings that this method, is that mechanical oscillation cause liquid
Drop has unstability, it is difficult to realizes stable laser output.The difficult control of drop is that restricting liquid drop laser is sent out for a long time
One key factor of exhibition.Therefore optical fiber optical tweezers technology is employed herein, is formed using planar end surface optical fiber staggered relatively
Ligh trap capture multiple drops, greatly strengthen the stability of drop resonator.
What we to be designed is a kind of multi-wavelength drop laser of incorporating light harvesting.She Jiang ripples in 2012 et al. devise
A kind of microballon immersion liquid laser and its thermal management algorithm (CN102868082A), its method are that laser activity is excellent
Rear-earth-doped solid state laser gain medium obtains microballon by optical manufacturing, and microballon is fixed in fluorescence flow cell and is soaked completely
Not in matching fluid.The technical solution uses inorganic compound as operation material, and the present invention is to use inorganic compound
Liquid is entrained in matching fluid fine droplet.Huang Shaohua in 2009 devises a kind of multiple-wavelength laser and preparation method thereof and should
The semiconductor laser of distributed feedback Bragg gratings structure is used with (CN101404384A).
