Ua ʻike anei ʻoe i nā ʻokoʻa ma waena o nā lasers Nanosecond, Picosecond a me Femtosecond?

Ua holomua wikiwiki ka ʻenehana laser i nā makahiki he ʻumi i hala iho nei. Mai ka laser nanosecond a i ka laser picosecond a i ka laser femtosecond, ua hoʻopili mālie ʻia i ka hana ʻoihana, e hāʻawi ana i nā hopena no nā ʻano āpau o ke ola. Akā pehea ka nui o kou ʻike e pili ana i kēia mau ʻano laser 3? E ʻike pū kākou:

Nā Wehewehena o nā Lasers Nanosecond, Picosecond, a me Femtosecond

Ua hoʻokomo mua ʻia ka laser Nanosecond i ke kahua ʻoihana i ka hopena o nā makahiki 1990 ma ke ʻano he mau laser diode-pumped solid-state (DPSS). Eia nō naʻe, he mana haʻahaʻa ko nā lasers mua o ia ʻano he mau watts a he nalu o 355nm. I ka hala ʻana o ka manawa, ua oʻo ka mākeke no nā lasers nanosecond, a ʻo ka hapa nui o nā lasers i kēia manawa he mau lōʻihi pulse i nā ʻumi a i nā haneli o nā nanoseconds.

ʻO ka laser Picosecond kahi laser ākea pulse pōkole loa e hoʻopuka ana i nā pulse pae picosecond. Hāʻawi kēia mau lasers i kahi laulā pulse pōkole loa, alapine hana hou hiki ke hoʻololi ʻia, ikehu pulse kiʻekiʻe, a kūpono no nā noi ma ka biomedicine, optical parametric oscillation, a me ke kiʻi microscopic biological. I nā ʻōnaehana kiʻi a me ka nānā ʻana o ka biology hou, ua lilo nā lasers picosecond i mau mea hana koʻikoʻi.

ʻO ka laser Femtosecond kahi laser pulse pōkole loa me ka ikaika kiʻekiʻe loa, i helu ʻia ma femtoseconds. Ua hāʻawi kēia ʻenehana holomua i nā kānaka i nā hiki hoʻokolohua hou i ʻike ʻole ʻia a he mau noi ākea. ʻO ka hoʻohana ʻana i kahi laser femtosecond ikaika loa, pōkole no nā kumu ʻike he mea pono loa ia no nā ʻano hana kemika like ʻole, me ka palena ʻole i ka ʻoki ʻana o ka pilina, ka hoʻokumu ʻana o ka pilina hou, ka hoʻoili proton a me ka electron, ka isomerization hui, ka dissociation molecular, ka wikiwiki, ke kihi, a me ka hoʻolaha ʻana o ke kūlana o nā mea waena o ka hopena a me nā huahana hope loa, nā hopena kemika e hana nei i nā hopena a me ka hopena o nā mea hoʻoheheʻe, a me ka mana o ka haʻalulu molecular a me ka wili ʻana i nā hopena kemika.

Nā ʻĀpana Hoʻololi Manawa no nā Nanoseconds, Picoseconds, a me Femtoseconds

1ns (nanosecond) = 0.0000000001 kekona = 10-9 kekona

1ps (picosecond) = 0.0000000000001 kekona = 10-12 kekona

1fs (femtosecond) = 0.0000000000000001 kekona = 10-15 kekona

Ua kapa ʻia nā lako hana laser nanosecond, picosecond, a me femtosecond i ʻike pinepine ʻia ma ka mākeke ma muli o ka manawa. ʻO nā mea ʻē aʻe, e like me ka ikehu pulse hoʻokahi, ka laulā pulse, ka alapine pulse, a me ka mana piko pulse, he kuleana ko lākou i ke koho ʻana i nā lako kūpono no ka hana ʻana i nā mea like ʻole. ʻO ka pōkole o ka manawa, ʻo ka emi ʻana o ka hopena ma ka ʻili o ka mea, e hopena ana i ka hopena hana maikaʻi.

Nā Hoʻohana Lapaʻau o nā Lasers Picosecond, Femtosecond, a me Nanosecond

Hoʻomehana koho nā lasers Nanosecond a luku i ka melanin i loko o ka ʻili, a laila hoʻopau ʻia mai ke kino e nā cell, e hopena ana i ka mae ʻana o nā ʻeha pigmented. Hoʻohana pinepine ʻia kēia ʻano hana no ka mālama ʻana i nā maʻi pigmentation. Hana nā lasers Picosecond i ka wikiwiki kiʻekiʻe, e wāwahi ana i nā ʻāpana melanin me ka ʻole e hōʻino i ka ʻili a puni. Hoʻōla maikaʻi kēia ʻano hana i nā maʻi pigmented e like me nevus o Ota a me Brown cyan nevus. Hana ka laser Femtosecond ma ke ʻano o nā pulses, hiki ke hoʻopuka i ka mana nui i ka manawa koke, maikaʻi loa no ka mālama ʻana i ka myopia.

ʻŌnaehana Hoʻoluʻu no nā Lasers Picosecond, Femtosecond, a me Nanosecond

ʻAʻohe mea ka nanosecond, picosecond a i ʻole femtosecond laser, pono e hōʻoia i ka hana maʻamau o ke poʻo laser a hoʻopili i nā lako me kahi mea hoʻolulu laser . ʻO ka pololei o nā lako laser, ʻoi aku ka kiʻekiʻe o ka pololei o ka kaohi mahana. TEYU Loaʻa i ka chiller laser ultrafast kahi paʻa o ka mahana o ±0.1°C a me ka hoʻomaʻalili wikiwiki, ka mea e hōʻoiaʻiʻo ai e hana ka laser ma kahi mahana mau a loaʻa kahi hopena kukuna paʻa, no laila e hoʻomaikaʻi ana i ke ola lawelawe o ka laser.TEYU nā mea hoʻolulu laser wikiwiki loa kūpono no kēia mau ʻano lako laser ʻekolu.
