Nd: YAG - Mea Lelei Mausali Laser
Fa'amatalaga o oloa
Nd: O le YAG o loʻo avea pea ma mea laser faʻamalo ma le faʻatinoga sili ona lelei.Nd:YAG lasers e fa'amama fa'apitoa e fa'aaoga ai se fa'amu uila po'o le laser diodes.
O se tasi lea o ituaiga sili ona taatele o le laser, ma e faʻaaogaina mo le tele o faʻaoga eseese.Nd: YAG lasers e masani ona fa'auluina le malamalama ma le galu o le 1064nm, i le infrared.Nd: YAG lasers o loʻo galue i le faʻaogaina ma le faʻaauau.Pulsed Nd: YAG lasers e masani lava ona faagaoioia i le faiga e taʻua o Q-switching mode: O se ki opitika o loʻo faʻaofi i totonu o le laser cavity e faʻatali mo le maualuga o le faitau aofaʻi o tagata i le neodymium ions aʻo leʻi tatalaina.
Ona mafai lea ona tafe atu le galu malamalama i totonu o le ana, depopulating le ala leisa fiafia i le tele o tagata inversion.I lenei faiga Q-switched, ua ausia le malosi o le gaosiga o le 250 megawatts ma le umi o le pulupulu o le 10 i le 25 nanoseconds ua ausia.[4]E mafai ona fa'aluaina fa'aluaina le malosi o le malosi e fa'atupu ai le malamalama leisa i le 532 nm, po'o le maualuga o le harmonics i le 355, 266 ma le 213 nm.
O le Nd: YAG laser rod na gaosia e la matou kamupani o loʻo i ai uiga o le maualuga o tupe maua, maualalo le laisa paepae, lelei le faʻafefeteina ma le vevela.E fetaui lelei mo le tele o auala galue (faʻaauau, pulupulu, Q-switch ma le loka loka).
E masani ona faʻaaogaina i le lata-mamao-infrared solid-state lasers, faʻaluaina taimi ma faʻasologa faʻatolu talosaga, E faʻaaogaina lautele i suʻesuʻega faasaienisi, togafitiga faafomaʻi, alamanuia ma isi fanua.
