Ndeapi akakosha maitiro e laser kuwana media?
Laser kuwana svikiro, inozivikanwawo selaser inoshanda chinhu, inoreva iyo sisitimu yemidziyo inoshandiswa kuwana chidimbu chehuwandu inversion uye kuburitsa inosimudzira mwaranzi kuti iwane kukwidziridzwa kwechiedza. Icho chikamu chepakati che laser, inotakura nhamba yakakura yeatomu kana mamorekuru, aya maatomu kana mamorekuru pasi pekunakidzwa kwesimba rekunze, anogona kuchinjika kuenda kunzvimbo yekunakidzwa, uye kuburikidza nekunakidzwa kwemwaranzi yakaburitswa mafotoni, nekudaro kugadzira a.laser chiedza. Iyo laser kuwana yepakati inogona kuve yakasimba, mvura, gasi kana semiconductor zvinhu.
Mune yakasimba-nyika lasers, iyo inowanzoshandiswa kuwana midhiya makristasi akaiswa neasingawanzo pasi ion kana shanduko yesimbi ions, senge Nd: YAG makristasi, Nd: YVO4 makristasi, etc. Mumvura lasers, organic dhayi anowanzoshandiswa sekuwana midhiya. Gasi lasers anoshandisa gasi senzira yekuwana, senge kabhoni dhaidhirodhi gasi mucarbon dioxide lasers, uye helium uye neon gasi muhelium-neon lasers.Semiconductor lasersshandisa semiconductor zvinhu seyepakati pekuwana, senge gallium arsenide (GaAs).
Akakosha maitiro eiyo laser kuwana medium anosanganisira:
Mamiriro edanho resimba: Maatomu kana mamorekuru ari muchikamu chekuwana anofanirwa kuve nechimiro chakakodzera chesimba resimba kuitira kuti uwane kudzoreredzwa kwevanhu pasi pekunakidzwa kwesimba rekunze. Izvi zvinowanzoreva kuti mutsauko wesimba pakati pesimba repamusoro uye rakaderera rinoda kuenderana nephoton simba reimwe wavelength.
Transition properties: Maatomu kana mamorekuru ari munzvimbo dzine mafaro anofanirwa kuve nekugadzikana kwekuchinja zvinhu kuitira kuti abudise mafotoni akabatana panguva yekunakidzwa nemwaranzi. Izvi zvinoda iyo yepakati kuti ive nepamusoro quantum kunyatsoshanda uye kurasikirwa kwakaderera.
Thermal kugadzikana uye simba remuchina: Mumashandisirwo anoshanda, iyo yepakati yekuwana inoda kumira yakakwira simba pombi mwenje uye laser kubuda, saka inoda kuve nekugadzikana kwemafuta uye simba remuchina.
Optical quality: Iyo optical mhando yekuwana yepakati yakakosha pakuita kwe laser. Inoda kuve nepamusoro mwenje transmittance uye yakaderera kuparadzira kurasikirwa kuti ive nechokwadi chemhando uye kugadzikana kweiyo laser beam. Sarudzo yelaser kuwana yepakati zvinoenderana nezvinodiwa zvekushandisa zvelaser, kushanda wavelength, simba rekubuda uye zvimwe zvinhu. Nekukwenenzvera zvinhu uye chimiro cheiyo svikiro rekuwana, kuita uye kugona kweiyo laser kunogona kuvandudzwa.
