Abstract
A double-layer cascade connection optical limiter is formed by a double-layer empty-chamber transparent container which accommodates the dimethyl formamide dispersion liquid of a single-walled carbon nanotube and the dimethyl formamide liquid solution of ZnPc. According to the double-layer cascade connection optical limiter, adjustment of an optical limiting curve is achieved due to adjustment of an arrangement sequence and the concentration of non-linear mediums. The double-layer cascade connection optical limiter can be applied to the laser protection field to protect human bodies or sensors from being damaged through hard lights.
Description
Technical field
The present invention relates to optical limiter, particularly a kind of Cascaded Double-layer optical limiter
Background technology
Laser is because the advantages such as its high strength, coherence, collimation are being brought into play more and more important effect in manufacture, medicine, science and technology, security fields.Yet laser is also a kind of light source of danger, and responsive optical device, human eye, skin etc. are had to destructive destruction, the use that therefore how to add light laser becomes safely the focus that current people pay close attention to.In order effectively to control the energy density of laser projection, people propose the concept of optical limiter (Optical limiter), have under high-light-energy metric density optical transmittance low, the high characteristic of transmitance under low optical energy density.This device allows to pass through lower than the light beam of default light intensity, but will stop passing through of light beam when light intensity optical limiter part when default, thereby avoids target object to be thereafter subject to the infringement of excess energy laser.Optical limiter part can be for the protection of optical sensor, and the security protection of Laser Experiments chamber human eye etc., are with a wide range of applications.
In recent years, people for make can practical application optical limiter, finding that nonlinear response is strong, aspect the material of response light spectrum width, made a large amount of effort.Nonlinear optical material for optical limiter is broadly divided into several classes such as nonlinear scattering (NLS) and anti-saturated absorption (RSA) by non-linear delustring mechanism at present.The former is as carbon nano-tube, and Graphene etc., are current very representative nonlinear scattering materials.Pertinent literature is as being published in < < Carbon nanotubes for optical limiting > > (the 10th phases 40 volume in 2002 of SCI periodical < < Carbon > >, 1789 1797 pages of –), wherein propose the light amplitude limiter based on carbon nano tube dispersion liquid, and used z scanning and pumping-detection method to do detailed performance characterization; And United States Patent (USP) < < BROADBAND OPTICAL LIMITER BASED ON NANO-GRAPHENE AND METHOD OF FABRICATING SAME > > (numbering: the optical limiter based on individual layer, few layer graphene and nanogold particle dispersion liquid of mentioning US20110304934A1).Optical limiter based on nonlinear scattering has stronger nonlinear response above, can be operated in ultraviolet to infrared broad wave band; And novel nano-material is compared traditional carbon black suspending liquid and is difficult for reuniting, and the stability of device is enhanced.Yet, because the mechanism of nonlinear scattering is limit, the simple mechanism of these single mechanism can only have obvious response to the significant laser of thermal effect (nanosecond or longer pulsewidth), and to the very weak even unglazed amplitude limit effect of ultrashort pulse (psec and following) response, in practical application, is restricted.The latter is as being published in < < Molecular Engineering of Peripherally And Axially Modified Phthalocyanines > > (the 15th phase of March in 2003 of SCI magazine < < Advanced Materials > >, 22-32 page) and < < Porphyrins and phthalocyanines as materials for optical limiting > > (the 3rd phases 141 volume in 2004 that is published in < < Synthetic Metals > >, 231-243 page), the phthalocyanine of studying in literary composition, porphyrin and metal derivative thereof are typical non-linear absorption materials, there are very large non-linear absorption coefficient and very fast response time, can be used in the lasing safety of ultrashort pulse.Yet non-linear absorption material depends on transition between molecular energy level, operation wavelength is generally narrower, as phthalocyanine is operated at visible light wave range (420nm～650nm), can not be used for separately manufacturing the optical limiter in broadband.
The general character of above homogenous material unitary system is also, the characteristic of light amplitude limit is determined by the characteristic of material itself, has so just limited greatly the space regulating.And in practical application, it is uncertain that the light intensity that target allows is irradiated.
In order to make up the shortcoming of the single mechanism of homogenous material, people have also studied conjugation and the non-conjugated mixing of two kinds of different nonlinear materials.< < Enhanced Optical Limiting Effects in Porphyrin-Covalently Functionalized Single-Walled Carbon Nanotubes > > (20 phases in 2008 in < < Advanced Materials > >, 511 515 pages of –) < < Linear and nonlinear spectroscopic studies of phthalocyanine-carbon nanotube blends > > (465 phases in 2008 and in < < Chemical Physic letters > >, 265-271 page), the non-linear nature of the carbon nano-tube solution of porphyrin functionalization (conjugation mixing) and carbon nano-tube phthalocyanine mixed liquor (non-conjugated mixing) characterizes respectively.The carbon nano-tube of porphyrin functionalization, due to the transferance of electronics between Porphyrin Molecule and carbon nano-tube, shows good non-linear nature.But this method preparation is complicated, needs accurate reaction conditions, and material category used is also restricted.Carbon nano-tube phthalocyanine mixed liquor (non-conjugated mixing) although can realize the light amplitude limit curve adjustment of part, yet that non-linear test shows its optical limiting properties is not good, can not meet the requirement of practical application.
