Erbium Glass Micro laser

Hoʻohana ʻia ka 1535nm ultra-small erbium glass eye-safe solid-state laser no ka laser ranging, a ʻo ka hawewe 1535nm aia wale nō ma ke kūlana o ka maka kanaka a me ka puka makani lewa, no laila ua loaʻa iā ia ka nānā nui ʻana i nā kahua o ka laser ranging. a me ka leka uila. ʻO ka laser aniani Erbium no ka helu haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa (emi iho ma mua o 10hz) mea ʻimi laser. Ua hoʻohana ʻia kā mākou lasers palekana maka i nā rangefinders me kahi ākea o 3-5km a me ke kūpaʻa kiʻekiʻe no ke kiʻi ʻana i nā mea kaua a me nā pahu drone.

Ke hoʻohālikelike ʻia me nā lasers Raman maʻamau a me nā lasers OPO (Optical Parametric Oscillation) e hoʻohua ai i nā lōʻihi nalu palekana, ʻo nā laser aniani maunu nā mea hana e hoʻopuka pololei i nā lōʻihi palekana maka, a loaʻa iā ia nā pōmaikaʻi o ka hana maʻalahi, ka maikaʻi o ke kukui maikaʻi, a me ka hilinaʻi kiʻekiʻe. ʻO ia ke kumu māmā i makemake ʻia no nā mea nānā maka.

ʻO nā lasers e hoʻokuʻu ana i nā lōʻihi nalu i ʻoi aku ma mua o 1.4 um i kapa ʻia ʻo "palekana maka" no ka mea ua komo ikaika ka mālamalama o kēia ʻano hawewe i loko o ka cornea a me ka lens o ka maka a no laila ʻaʻole hiki ke hōʻea i ka retina koʻikoʻi loa. ʻIke loa, ʻo ka maikaʻi o ka "palekana maka" ʻaʻole i hilinaʻi wale i ka lōʻihi o ka hawewe hoʻokuʻu, akā i ka pae mana a me ka ikaika māmā e hiki ke hiki i ka maka. He mea koʻikoʻi loa nā lasers-palekana i ka laser ranging 1535nm a me ka radar, kahi e pono ai ka māmā e hele i kahi mamao ma waho. ʻO nā laʻana e pili ana i nā mea hoʻokalakupua laser a me nā kamaʻilio optika manuahi.
