Chii chinonzi diode laser?

Diode laser mudziyo wemagetsi unoshandisa PN junction nezvinhu zve binary kana ternary semiconductor. Kana voltage ikashandiswa kunze, maerekitironi anochinja kubva ku conduction band kuenda ku valence band oburitsa simba, nokudaro achigadzira ma photon. Kana ma photon aya achidzokorora kakawanda mu PN junction, anoburitsa laser beam yakasimba. Semiconductor lasers dzine hunhu hwe miniaturization uye kuvimbika kwakanyanya, uye laser frequency yavo inogona kugadziriswa nekuchinja material composition, PN junction size, uye control voltage.

Ma laser e diode anoshandiswa zvakanyanya munzvimbo dzakadai se fiber optic communication, optical discs, laser printers, laser scanners, laser indicators (laser pens), nezvimwewo. Ndiwo ma laser makuru pahuwandu hwekugadzirwa. Pamusoro pezvo, ma laser e semiconductor ane mashandisirwo akawanda mu laser ranges, LiDAR, laser communication, laser simulation weapons, laser yambiro, laser guidance and tracking, ignition and blasting, automatic control, detection instruments, nezvimwewo, zvichigadzira musika wakakura.
