Iiparamitha zamandla kunye nokusebenza

Iilaser ezikhawulezayo zibonakaliswa ziiparameter ezimbini zamandla eziphambili:

1. Amandla Aphakathi: Aqala kwi-milliwatts ezilishumi ukuya kwi-watts ezininzi nangaphezulu, kuxhomekeke kwiimfuno zokusetyenziswa.

2. Amandla Aphezulu: Ngenxa yexesha elifutshane kakhulu lokubetha kwentliziyo, amandla aphezulu anokufikelela kwiikilowatts ezininzi ukuya kumakhulu eekilowatts. Umzekelo, ezinye iilaser ze-femtosecond zigcina amandla aphakathi kwe-1W, ngelixa amandla azo aphezulu ee-oda ezininzi eziphezulu.

Ezinye izalathisi zokusebenza ezibalulekileyo ziquka izinga lokuphindaphinda kwe-pulse, amandla e-pulse, kunye nobubanzi be-pulse, zonke ezimele zilungiswe ngokusekelwe kwiimfuno ezithile zoshishino kunye nophando.

Abavelisi Abaphambili kunye noPhuhliso lweShishini

Abavelisi abaninzi behlabathi balawula ishishini le-laser ye-ultrafast:
