Li-Lasers tsa Ultrafast ke eng, 'me li sebelisoa joang?

Tlhaloso ea Ultrafast Lasers

Li-laser tsa Ultrafast li bua ka lilaseser tse ntšang maqhubu a makhutšoane haholo, hangata li le picosecond (10⁻¹² seconds) kapa femtosecond (10⁻¹⁵ seconds). Ka lebaka la nako ea bona ea nako e khuts'oane ea pulse, li-lasers tsena li sebelisana le lisebelisoa haholo-holo ka liphello tse sa chesehang, tse sa tsitsang, tse fokotsang haholo ho hasana ha mocheso le tšenyo ea mocheso. Tšobotsi ena e ikhethang e etsa hore li-lasers tsa ultrafast e be tse loketseng hantle bakeng sa micromachining e nepahetseng, mekhoa ea bongaka le lipatlisiso tsa mahlale.

Lisebelisoa tsa Ultrafast Lasers

Ka matla a bona a phahameng a tlhoro le tšusumetso e fokolang ea mocheso, li-lasers tsa ultrafast li sebelisoa haholo liindastering tse fapaneng, ho kenyeletsoa.:

1. Indasteri Micromachining: Li-lasers tsa Ultrafast li thusa ho itšeha, ho cheka, ho tšoaea le ho sebetsa ka holim'a metsi maemong a manyane le a nano a nang le libaka tse fokolang tse amehang ke mocheso.

2. Litšoantšo tsa Bongaka le tsa Biomedical: Ho ophthalmology, li-laser tsa femtosecond li sebelisoa bakeng sa opereishene ea mahlo ea LASIK, e fanang ka ho itšeha ka nepo le mathata a fokolang a kamora ho buuoa. Ho feta moo, li sebelisoa ho microscope ea multiphoton le tlhahlobo ea lisele tsa biomedical.

3. Patlisiso ea Mahlale: Li-lasers tsena li bapala karolo ea bohlokoa ho spectroscopy e rarollotsoeng ka nako, li-nonlinear optics, taolo ea quantum, le lipatlisiso tse ncha tsa lisebelisoa, tse lumellang bo-ramahlale ho hlahloba matla a matla maemong a athomo le a limolek'hule.

4. Lipuisano tsa Optical: Li-laser tse ling tsa ultrafast, tse kang 1.5μm fiber lasers, li sebetsa ka har'a sehlopha sa puisano sa fiber ea tahlehelo e tlaase, e sebetsang e le mehloli ea leseli e tsitsitseng bakeng sa phetiso ea data ka lebelo le phahameng.

Mekhahlelo ea Matla le Ts'ebetso

Li-lasers tsa Ultrafast li khetholloa ke likarolo tse peli tsa bohlokoa tsa matla:

1. Karolelano ea Matla: Ho tloha ho mashome a li-milliwatt ho isa ho li-watts tse 'maloa kapa ho feta, ho latela litlhoko tsa kopo.

2. Peak Power: Ka lebaka la nako e khuts'oane ea ho otla ha pelo, matla a phahameng a ka fihla ho li-kilowatts tse 'maloa ho isa ho li-kilowatt tse makholo. Mohlala, li-laser tse ling tsa femtosecond li boloka matla a mahareng a 1W, athe matla a tsona a holimo ke liodara tse 'maloa tsa boholo bo holimo.

Matšoao a mang a bohlokoa a ts'ebetso a kenyelletsa sekhahla sa ho pheta-pheta ha sekhahla, matla a ho otla ha pelo, le bophara ba sekhahla, tseo kaofela li tlamehang ho ntlafatsoa ho ipapisitsoe le litlhoko tse ikhethang tsa indasteri le lipatlisiso.

Baetsi ba ka Sehloohong le Ntlafatso ea Indasteri

Baetsi ba 'maloa ba lefats'e ba laola indasteri ea laser e potlakileng haholo:

1. Coherent, Spectra-Physics, Newport (MKS) - Likhamphani tse thehileng tse nang le theknoloji e holileng tsebong le mefuta e mengata ea likopo tsa indasteri le tsa mahlale.

2. TRUMPF, IPG Photonics - Baetapele ba 'maraka ba tharollo ea laser ea indasteri.

3. Baetsi ba Machaena (Han's Laser, GaussLasers, YSL Photonics) - Libapali tse ntseng li hlaha li hatela pele haholo ho thehoeng ha laser, mahlale a ho notlela mokhoa, le ho kopanya tsamaiso.

Mekhoa ea ho Pholisa le Tsamaiso ea Mocheso

Leha a na le matla a tlase, li-laser tse potlakileng haholo li hlahisa mocheso o mongata hang hang ka lebaka la matla a tsona a holimo. Mekhoa e metle ea ho pholisa e bohlokoa ho netefatsa ts'ebetso e tsitsitseng le bophelo bo bolelele ba ts'ebetso.

Chiller Systems: Li-laser tsa Ultrafast hangata li na le li-chiller tsa indasteri tse nang le taolo e nepahetseng ea mocheso oa ± 0.1 ° C kapa ho feta ho boloka ts'ebetso e tsitsitseng ea laser.

TEYU CWUP-letoto la li-Chillers : E etselitsoe ka ho khetheha bakeng sa ho pholisa ka laser ka potlako, li-laser chiller tsena li fana ka taolo ea mocheso e laoloang ke PID ka ho nepahala ho fihla ho 0.08°C ho isa ho 0.1°C. Ba boetse ba tšehetsa puisano ea RS485 bakeng sa ho shebella le ho laola hole, ho etsa hore e be tse loketseng bakeng sa lisebelisoa tsa laser tsa 3W -60W ultrafast laser.

Mekhoa ea Bokamoso ea Ultrafast Lasers

Indasteri ea laser e potlakileng e ntse e tsoela pele:

1. Li-Pulse tse Khutšoane, Matla a Phahameng a Phahameng: Khatelo-pele e tsoelang pele ea ho notlela mokhoa oa ho notlela le khatello ea pulse e tla nolofalletsa li-lasers tsa attosecond pulse bakeng sa lits'ebetso tse nepahetseng haholo.

2. Modular le Compact Systems: Li-lasers tsa nakong e tlang tsa ultrafast li tla kopanngoa le ho sebelisoa habonolo, li fokotsa ho rarahana le litšenyehelo tsa ts'ebeliso.

3. Lits'enyehelo tse Tlase le Boikemisetso ba Sebaka: Ha likarolo tsa bohlokoa tse kang likristale tsa laser, mehloli ea pompo, le lits'ebetso tsa pholileng li hlahisoa ka har'a naha, litšenyehelo tsa laser tsa ultrafast li tla theoha, ho nolofalletsa ho amoheloa ka bongata.

4. Cross-Industry Integration: Li-lasers tsa Ultrafast li tla kopana haholoanyane le masimo a kang puisano ea optical, tlhahisoleseling ea quantum, machining e nepahetseng, le lipatlisiso tsa biomedical, tse tsamaisang mekhoa e mecha ea theknoloji.

Qetello

Theknoloji ea laser ea Ultrafast e tsoela pele ka potlako, e fana ka ho nepahala ho ke keng ha bapisoa le liphello tse fokolang tsa mocheso ho pholletsa le indasteri, bongaka le saense. Baetsi ba etelletseng pele ba tsoela pele ho nchafatsa liparamente tsa laser le mekhoa ea ho kopanya ha tsoelopele ea litsamaiso tse pholileng le tsa taolo ea mocheso li matlafatsa botsitso ba laser. Ha litšenyehelo li ntse li fokotseha le lits'ebetso tsa indasteri e fapaneng li ntse li hola, li-laser tsa ultrafast li ikemiselitse ho fetola liindasteri tse ngata tsa theknoloji e phahameng.
