He aha ka laser diode?

ʻO ka laser diode kahi mea uila e hoʻohana ana i kahi hui PN me nā mea semiconductor binary a i ʻole ternary. Ke hoʻohana ʻia ka volta ma waho, e hoʻololi nā electrons mai ka hui conduction i ka valence band a hoʻokuʻu i ka ikehu, a laila e hana ana i nā photons. Ke ʻike pinepine kēia mau kiʻi kiʻi i ka hui PN, e poha lākou i kahi kukuna laser ikaika. Loaʻa i nā laser Semiconductor nā hiʻohiʻona o ka miniaturization a me ka hilinaʻi kiʻekiʻe, a hiki ke hoʻoponopono ʻia ko lākou alapine laser ma o ka hoʻololi ʻana i ka haku mele, ka nui o ka junction PN, a me ka mana mana.

Hoʻohana nui ʻia nā lasers diode i nā kula e like me ka fiber optic communication, optical discs, laser printers, laser scanners, laser indicators (laser pens), etc. Eia kekahi, he nui nā noi o nā laser semiconductor i ka laser ranging, LiDAR, ke kamaʻilio laser, nā mea kaua simulation laser, ka ʻōlelo aʻoaʻo laser, ka alakaʻi a me ka nānā ʻana, ka ʻāʻī a me ka detonation, ka mana aunoa, nā mea ʻike, a me nā mea ʻē aʻe, e hana ana i kahi mākeke ākea.
