Chii chinonzi laser?
Muchidimbu, laser chiedza chinogadzirwa nekukwezvwa kwezvinhu. Uye tinogona kuita basa rakawanda nelaser beam.
MuWikipedia, A lasermudziyo unoburitsa chiedza kuburikidza nekushanda kwechiedza uchishandisa nzira yekuwedzera chiedza zvichibva pakuburitswa kwemwaranzi yemagetsi inosimudzirwa. Izwi rekuti "laser" ipfupiso ye "kuwedzera chiedza kuburikidza nekuburitswa kwemwaranzi inosimudzirwa". Laser yekutanga yakagadzirwa muna 1960 naTheodore H. Maiman kuHughes Research Laboratories, zvichibva pabasa redzidziso raCharles Hard Townes naArthur Leonard Schawlow.
Laser yakasiyana nedzimwe nzvimbo dzechiedza nekuti inoburitsa chiedza chakabatana. Kubatana kwenzvimbo kunobvumira laser kuti ionekwe panzvimbo yakaoma, zvichiita kuti mashandisirwo akadai sekucheka nelaser uye lithography. Kubatana kwenzvimbo kunobvumirawo laser beam kuti irambe yakamanikana padaro refu (collimation), zvichiita kuti mashandisirwo akadai sema laser pointers nelidar arambe akamanikana. Ma laser anogonawo kuva nekubatana kwenguva refu, izvo zvinovabvumira kuburitsa chiedza nespectrum yakamanikana zvikuru. Neimwe nzira, kubatana kwenguva kunogona kushandiswa kugadzira ultrashort pulses yechiedza ne broad spectrum asi nguva yacho ipfupi se femtosecond.
MaLaser anoshandiswa mumadhiraivha edhisiki e optical, maprinta elaser, mabarcode scanners, maDNA sequencing instruments, fiber-optic, semiconducting chip manufacturing (photolithography), uye free-space optical communication, laser surgery, uye ganda treatments, cutting and welding materials, military and police enforcement devices for marking targets and measure range and speed, uye mu laser lighting displays for varaidzo.
Mushure mekugadzirwa kwetekinoroji yelaser kwenguva refu, laser inogona kushandiswa muindasitiri dzakasiyana siyana, uye imwe yenzira dzinonyanya kushandiswa kana muindasitiri yekucheka, pasina simbi, indasitiri yesimbi kana isiri yesimbi, muchina wekucheka laser unovandudza nzira yekucheka yechinyakare, kuvandudza mashandiro ekugadzira akawanda eindasitiri yezvigadzirwa, senge mbatya, machira, makapeti, huni, acrylic, kushambadzira, kushanda kwesimbi, mota, midziyo yekusimba uye maindasitiri efenicha.
Laser yakava imwe yezvishandiso zvekucheka zvakanakisa nekuda kwehunyanzvi hwayo hwekucheka hwakarurama uye hunokurumidza.
