Cr4+:YAG -Sesebediswa se Loketseng Bakeng sa ho Fetola Q-switching
Tlhaloso ea Sehlahisoa
Crystal Passive Q-switch e ratoa bakeng sa ho nolofatsa tlhahiso le ts'ebetso, litšenyehelo tse tlase, le ho fokotsa boholo ba sistimi le boima ba 'mele.
Cr4 +: YAG e tsitsitse ka lik'hemik'hale, e hanyetsa UV 'me e tšoarella nako e telele. Cr4+: YAG e tla sebetsa holim'a mefuta e fapaneng ea mocheso le maemo.
Ts'ebetso e ntle ea mocheso oa Cr4 +: YAG e loketse hantle lits'ebetso tsa motlakase tse mahareng.
Liphetho tse ntle li bonts'itsoe ho sebelisoa Cr4+:YAG joalo ka ha ho feto-fetoha ha Q-switch bakeng sa Nd:YAG lasers. Phatlalatso ea phallo e lekantsoe hore e ka ba 0.5 J/cm2. Nako e liehang ea ho hlaphoheloa ea 8.5 µs, ha e bapisoa le lidae, e na le thuso bakeng sa ho thibela mokhoa oa ho notlela.
Q-switched pulsewidths ea 7 ho 70 ns le litekanyetso tsa ho pheta-pheta ho fihla ho 30 Hz li fihletsoe. Liteko tsa Laser Damage Threshold li bonts'itse AR e koahetsoe ke Cr4+: YAG passive Q-switches e feta 500 MW/cm2.
Boleng ba optical le homogeneity ea Cr4 +: YAG e ntle haholo. Ho fokotsa tahlehelo ea ho kenya likristale li koahetsoe ka AR. Cr4 +: Likristale tsa YAG li fanoa ka bophara bo tloaelehileng, le mefuta e mengata ea likhahla tsa mahlo le bolelele ho lumellana le litlhaloso tsa hau.
E ka boela ea sebelisoa ho ikopanya le Nd: YAG le Nd, Ce: YAG, boholo bo tloaelehileng joalo ka D5 * (85 + 5)
Melemo ea Cr4+:YAG
● Botsitso bo phahameng ba lik'hemik'hale le ho tšepahala
● Ho ba bonolo ho sebetsa
● Boemo bo phahameng ba tšenyo (> 500MW/cm2)
● E le matla a phahameng, boemo bo tiileng le compact passive Q-Switch
● Nako e telele ea bophelo le conductivity e ntle ea mocheso
