ʻO ka laser Femtosecond kahi laser e hana ana i nā pulses me ka manawa pōkole loa (10-15s) a me ka mana kiʻekiʻe. ʻAʻole wale ia e hiki ai iā mākou ke loaʻa i ka hoʻonā manawa ultra-pōkole akā pū kekahi, no kona mana kiʻekiʻe kiʻekiʻe, ua hoʻomohala nui ʻia i nā ʻano ʻoihana like ʻole.
ʻO kafemtosecond titanium pōhaku pōhaku laser, nona ka oscillator laser femtosecond a me ka amplifier laser femtosecond, ʻo ia ka laser maʻamau i hoʻohana ʻia no nā noi e hiki ke hoʻoulu i nā pulses femtosecond-scaled. Ma o ka loina paʻa ponoʻī opōhaku makamae titaniuma me ka ʻenehana kiʻekiʻe kiʻekiʻe o ka honua chirped pulse amplification (CPA), hiki ke hana pololei i nā pulse laser o kekahi mau femtoseconds me ka mana kiʻekiʻe o nā terawatts.
I ka hoʻohana ʻana i nā lasers femtosecond ua hoʻolaha nui ʻia i nā ʻano like ʻole, ʻo nā lasers a me nā ʻenehana i hiki ke hoʻohua i nā femtoseconds ua hana pū kekahi i kekahi mau hanauna o ka hana hou. Mai nā lasers dye a hiki i nā lasers solid-state, mai Q-modulation a hiki i ka ʻenehana paʻa i ka mode-locked, a me ka hoʻohana ʻana i ka ʻenehana paʻa paʻa ponoʻī e hiki ai ke hana i nā pulu pōkole i kēia lā, ua hoʻomohala ʻia ka ʻenehana pulse ultrashort ma ka lele a me nā palena i kahi wale nō. he mau makahiki. Iwaena o lakou,nā lasers sapphire titanium-dopedme ka ʻenehana hoʻopaʻa pono-mode he kumuhana wela i ka ʻenehana pulse ultrashort.
Hāʻawi ʻia i ka laulā fluorescence spectrum onā kristal sapphire titanium-doped, inā paʻa ke ʻano longitudinal o ka laser, hiki i ke theoretically ke hana pololei i nā femtoseconds o ka puka pulse, me ka ʻole o ka pono e koho i kahi ʻenehana hoʻopili ākea pulse, ʻaʻole i loaʻa i nā laser ʻē aʻe. Ma Kina, ʻo ka noiʻi a me ka hoʻohana ʻana i nā lasers sapphire titanium-doped, ʻoiai aia ka nui o ka hoʻomohala ʻana, ma kanā laser pōhaku makamae titaniumma na buke Pake a he kakaikahi loa ka heluhelu ana. ʻO kēia pepaShanghai Xinkehui New Material Co., Ltd hāʻawi i ka systematic exposition ma ka hana kumu o ka titanium gemstone laser mai titanium gemstone laser oscillator, titanium-doped sapphire loaʻa nā hiʻohiʻona, paʻa ponoʻī kumu, dispersion, a me kāna titanium gemstone laser amplifier.
No laila, ʻo ka manaʻo o kēia pepa, ʻo ia ka loaʻa ʻana o ka hōʻike kikoʻī a puninā laser femtosecond, kā lākou kumu hana, ʻano, a me ka hoʻohana ʻana i kahi hōʻuluʻulu maʻamau, i hoʻohana ʻia e hoʻonui i ka ʻike o ka femtosecondnā laser pōhaku makamae titanium.
Ma hope e hoʻomau mākou i ka hoʻonui hou aku iā ʻoe e pili ana i ka ʻike pili i ka kristal laser, hiki iā ʻoe ke hoʻolohe mau iā mākou, inā makemake ʻoe, e ʻoluʻolu e kelepona i kā mākou limahana kūʻai!
