Alexandrite Laser 755nm

Kodi laser ndi chiyani?

LASER (kukulitsa kuwala ndi kusonkhezeredwa kutulutsa ma radiation) imagwira ntchito potulutsa kuwala kwamphamvu kwamphamvu, komwe kukakhala pakhungu linalake kumapangitsa kutentha ndikuwononga maselo odwala. Kutalika kwa mafunde kumayesedwa mu nanometers (nm).

Mitundu yosiyanasiyana ya lasers ilipo kuti igwiritsidwe ntchito pakuchita opaleshoni yapakhungu. Amasiyanitsidwa ndi sing'anga yomwe imapanga mtengo wa laser. Iliyonse mwa mitundu yosiyanasiyana ya ma lasers imakhala ndi mawonekedwe ake osiyanasiyana, kutengera kutalika kwake komanso malowedwe ake. Sing'angayo imakulitsa kuwala kwa utali winawake wautali pamene ikudutsamo. Izi zimabweretsa kumasulidwa kwa photon ya kuwala pamene ikubwerera ku chikhalidwe chokhazikika.

Kutalika kwa mphamvu ya kuwala kumakhudza momwe laser amagwiritsira ntchito opaleshoni yapakhungu.

Kodi laser alexandrite ndi chiyani?

Laser ya alexandrite imapanga kuwala kwapadera mu mawonekedwe a infrared (755 nm). Zimaganiziridwalaser kuwala kofiira. Ma laser a Alexandrite amapezekanso mu Q-switched mode.

Kodi laser ya alexandrite imagwiritsidwa ntchito bwanji?
