Laser fiber.
Hāʻawi nā laser fiber i kahi ala maikaʻi loa e hoʻololi i ka ʻōlinolino o nā laser semiconductor mana kiʻekiʻe.ʻOiai hiki i nā optics multiplexing wavelength ke hoʻololi i nā lasers semiconductor haʻahaʻa haʻahaʻa i ʻoi aku ka mālamalama, hiki mai kēia ma ke kumu kūʻai o ka laulā spectral a me ka paʻakikī photomechanical.Ua hōʻoia ʻia ka maikaʻi o nā laser fiber i ka hoʻololi ʻana o ka mālamalama.

Hoʻokomo ʻia nā fibers pālua ʻelua i ka makahiki 1990, me ka hoʻohana ʻana i kahi kumu hoʻokahi-mode i hoʻopuni ʻia e ka multimode cladding, hiki ke hoʻolauna maikaʻi i ka mana kiʻekiʻe, haʻahaʻa haʻahaʻa multimode semiconductor pump lasers i loko o ka fiber, e hana ana i kahi ala ʻoi aku ka waiwai e hoʻohuli i nā laser semiconductor mana kiʻekiʻe. i loko o nā kumu kukui māmā.No nā fibers ytterbium-doped (Yb), hoʻohauʻoli ka paila i kahi pūnaʻi absorption ākea i kikowaena ma 915nm, a i ʻole kahi hui absorption haiki kokoke i 976nm.I ka hoʻokokoke ʻana o ka nalu pume i ka nalu lasing o ka laser fiber, ua hoʻemi ʻia ka mea i kapa ʻia ʻo quantum deficit, hoʻonui i ka pono a hoʻemi i ka nui o ka wela wela e pono e hoʻopau ʻia.

Nā laser fibera me nā lasers paʻa paʻa paʻa diode e hilinaʻi nei i ka piʻi ʻana o ka mālamalama o kalaser diode.Ma keʻano laulā, ke hoʻomau nei ka ʻōlinolino o nā lasers diode, e hoʻonui pū ka mana o nā lasers a lākou e pahū ai.ʻO ka hoʻomaikaʻi ʻana o ka ʻōlinolino o nā laser semiconductor e hoʻoikaika i ka hoʻololi ʻana o ka mālamalama.

E like me kā mākou e manaʻo ai, pono ka ʻōlinolino a me nā kikoʻī no nā ʻōnaehana e hiki mai ana e hiki ai ke hoʻoheheʻe haʻahaʻa haʻahaʻa haʻahaʻa no nā hiʻohiʻona absorption haiki i nā lasers solid-state, a me nā papahana hoʻohana hou i ka lōʻihi hawewe no nā noi laser semiconductor pololei.

Kiʻi 2: Hoʻonui ʻia ka ʻōlinolino o ka mana kiʻekiʻenā laser semiconductorhiki ke hoʻonui i nā noi

Makeke a me ka noi

ʻO nā holomua i nā laser semiconductor kiʻekiʻe i hana i nā noi koʻikoʻi he nui.No ka mea ua hoʻemi nui ʻia ke kumukūʻai no kēlā me kēia kukui uila o nā laser semiconductor kiʻekiʻe, ua hoʻololi kēia mau laser i nā ʻenehana kahiko a hiki i nā ʻano huahana hou.

Me ka hoʻomaikaʻi ʻana o ke kumukūʻai a me ka hana ma mua o 10-fold i kēlā me kēia ʻumi makahiki, ua hoʻopau nā laser semiconductor kiʻekiʻe i ka mākeke ma nā ala i manaʻo ʻole ʻia.ʻOiai he paʻakikī ke wānana i nā noi e hiki mai ana me ka pololei, he mea aʻoaʻo nō hoʻi ke nānā i hope i nā makahiki he ʻekolu i hala aku nei e noʻonoʻo i nā hiki o nā makahiki he ʻumi e hiki mai ana (e nānā i ke Kiʻi 2).

I ka hōʻike ʻana o Hall i nā laser semiconductor ma mua o 50 mau makahiki i hala aku nei, ua hoʻokumu ʻo ia i kahi hoʻololi ʻenehana.E like me ke kānāwai o Moore, ʻaʻohe mea i wānana i nā hoʻokō maikaʻi loa o nā laser semiconductor mana kiʻekiʻe i ukali ʻia me nā ʻano hana hou like ʻole.

ʻO ka wā e hiki mai ana o nā laser semiconductor
ʻAʻohe kānāwai koʻikoʻi o ka physics e hoʻokele ana i kēia mau hoʻomaikaʻi ʻana, akā ʻo ka holomua ʻana o ka ʻenehana e hoʻomau i kēia hoʻomohala exponential i ka nani.E hoʻomau nā laser Semiconductor e pani i nā ʻenehana kuʻuna a e hoʻololi hou i ke ʻano o ka hana ʻana.ʻOi aku ka mea nui no ka ulu ʻana o ka hoʻokele waiwai, e hoʻololi pū nā laser semiconductor kiʻekiʻe i ka mea hiki ke hana.
