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 ternary paha. Ke hoʻopili ʻia kahi voltage ma waho, neʻe nā electrons mai ke kāʻei conduction i ke kāʻei valence a hoʻokuʻu i ka ikehu, a laila e hana ana i nā photons. Ke hōʻike pinepine ʻia kēia mau photons i ka hui PN, e pahū lākou i kahi kukuna laser ikaika. Loaʻa i nā lasers Semiconductor nā ʻano o ka miniaturization a me ka hilinaʻi kiʻekiʻe, a hiki ke hoʻoponopono ʻia ko lākou alapine laser ma ka hoʻololi ʻana i ka haku mele mea, ka nui o ka hui PN, a me ka voltage kaohi.

Hoʻohana nui ʻia nā lasers diode ma nā kahua e like me ke kamaʻilio fiber optic, nā disc optical, nā mīkini paʻi laser, nā scanner laser, nā ʻōkuhi laser (nā peni laser), a pēlā aku. ʻO lākou ka laser nui loa ma ke ʻano o ka nui o ka hana. Eia kekahi, he nui nā noi o nā lasers semiconductor ma ka laser ranging, LiDAR, kamaʻilio laser, nā mea kaua simulation laser, ka ʻōlelo aʻo laser, ke alakaʻi laser a me ka hahai ʻana, ka hoʻā ʻana a me ka detonation, ka mana aunoa, nā mea ʻike, a pēlā aku, e hana ana i kahi mākeke ākea.
