LBO Crystal
LBO (LiB3O5) ke mofuta oa kristale ea sefahleho e senang mohala e nang le li-transmittance tse ntle tsa ultraviolet (210-2300 nm), sebaka se phahameng sa tšenyo ea laser le ts'ebetso e kholo ea frequency e pheta-phetoang (hoo e ka bang makhetlo a 3 a kristale ea KDP). Kahoo LBO e sebelisoa hangata ho hlahisa matla a phahameng a bobeli le a boraro kotsi ea laser, haholo bakeng sa li-laser tsa ultraviolet.
LBO e na le lekhalo le leholo la band band le ponaletso ea tikoloho, ho kopanya ho phahameng ho sa amaneng, thepa e ntle ea lik'hemik'hale le thepa. Litšobotsi tsena li etsa hore kristale ena e khone ho sebetsana le li-process tsa parametric (OPO / OPA) le mekhahlelo e sa amaneng le maemo (NCPM), le eona.
Ikopanye le rona bakeng sa tharollo e nepahetseng bakeng sa ts'ebeliso ea hau ea likristale tsa LBO.
