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 tlhoro e phahameng le tšusumetso e fokolang ea mocheso, li-lasers tsa ultrafast li sebelisoa haholo liindastering tse fapaneng, ho kenyelletsa:

1. Indasteri ea Micromachining: Li-lasers tsa Ultrafast li nolofalletsa ho itšeha ka mokhoa o nepahetseng, ho cheka, ho tšoaea, le ho sebetsa ka holim'a maemo a manyenyane le a nano a nang le libaka tse fokolang tsa mocheso.

2. Litšoantšo tsa Bongaka le Likokoana-hloko: Ho ophthalmology, lasers ea femtosecond e sebelisetsoa ho buuoa ka leihlo la LASIK, ho fana ka ho itšeha ka mokhoa o nepahetseng oa cornea le mathata a fokolang ka mor'a 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 phetha karolo ea bohlokoa ho spectroscopy e rarollotsoeng ka nako, li-nonlinear optics, taolo ea quantum, le lipatlisiso tse ncha tsa thepa, ho lumella bo-rasaense ho hlahloba matla a maholo ka ho fetisisa maemong a athomo le a limolek'hule.

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

Mekhahlelo ea Matla le Ts'ebetso

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

1. Karolelano ea Matla: E tloha ho mashome a li-milliwatt ho isa ho li-watts tse 'maloa kapa ho feta, ho itšetlehile ka 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 ea ultrafast:

1. Coherent, Spectra-Physics, Newport (MKS) - Lik'hamphani tse thehiloeng tse nang le theknoloji e hōlileng tsebong le mekhoa e mengata ea liindasteri le tsa saense.

2. TRUMPF, IPG Photonics - Baeta-pele ba 'maraka ba litharollo tsa lisebelisoa tsa laser tsa indasteri.

3. Baetsi ba Machaena (Han's Laser, GaussLasers, YSL Photonics) - Libapali tse ntseng li hlaha li etsa tsoelo-pele e kholo ho thehoeng ha laser, mekhoa ea 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-lasers 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 ea laser e tsitsitseng.

TEYU CWUP-Series Chillers : E etselitsoe ka ho khetheha bakeng sa pholileng ea laser e potlakileng haholo, li-laser chillers 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 ho ea ho:

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

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

3. Litšenyehelo tse Tlaase le ho Etsa Sebaka: Ha likarolo tsa bohlokoa tse kang likristale tsa laser, mehloli ea pompo, le lisebelisoa tsa ho pholisa li hlahisoa ka hare ho naha, litšenyehelo tsa laser tse potlakileng li tla theoha, ho nolofaletsa ho amoheloa ka bongata.

4. Cross-Industry Integration: Li-lasers tsa Ultrafast li tla kopana ka ho eketsehileng le masimo a kang puisano ea optical, tlhahisoleseding ea quantum, machining e nepahetseng, le lipatlisiso tsa biomedical, ho khanna 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 ka sehloohong ba tsoela pele ho ntlafatsa liparamente tsa laser le mekhoa ea ho kopanya ha tsoelo-pele ea tsamaiso ea pholileng le ea mocheso e 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.
