He aha ka laser CW DPSS? Wehewehena Wehewehe

Nalu Hoʻomau (CW):Pili kēia i ke ʻano hana o ka laser. Ma ke ʻano CW, hoʻopuka ka laser i kahi kukuna mālamalama paʻa a mau, i kūʻē i nā lasers pulsed e hoʻopuka ana i ka mālamalama i nā pahū. Hoʻohana ʻia nā lasers CW i ka wā e pono ai kahi puka kukui mau a paʻa, e like me ke ʻoki ʻana, ka hoʻoheheʻe ʻana, a i ʻole nā ​​noi kālai ʻana.

Ka hoʻopili ʻana o Diode:I loko o nā lasers diode-pumped, ʻo ka ikehu i hoʻohana ʻia e hoʻonāukiuki i ka medium laser e hoʻolako ʻia e nā diodes laser semiconductor. Hoʻopuka kēia mau diodes i ka mālamalama i omo ʻia e ka medium laser, e hoʻonāukiuki ana i nā ʻātoma i loko a ʻae iā lākou e hoʻopuka i ka mālamalama kūlike. ʻOi aku ka maikaʻi a me ka hilinaʻi o ka pumping diode i hoʻohālikelike ʻia me nā ʻano hana pumping kahiko, e like me nā kukui uila, a ʻae i nā hoʻolālā laser ʻoi aku ka liʻiliʻi a paʻa.

Laser Kūlana Paʻa:ʻO ka huaʻōlelo "solid-state" e pili ana i ke ʻano o ka gain medium i hoʻohana ʻia i loko o ka laser. ʻAʻole e like me nā lasers kinoea a wai paha, hoʻohana nā lasers solid-state i kahi mea paʻa ma ke ʻano he medium. ʻO kēia medium he kristal maʻamau, e like me Nd:YAG (Neodymium-doped Yttrium Aluminum Garnet) a i ʻole Ruby, i hoʻohui ʻia me nā mea honua kakaikahi e hiki ai ke hana i ka mālamalama laser. ʻO ke kristal doped ka mea e hoʻonui ai i ka mālamalama e hana i ke kukuna laser.

Nā Nalu a me nā Hana:Hiki i nā lasers DPSS ke hoʻopuka i nā nalu like ʻole, ma muli o ke ʻano o ka mea doping i hoʻohana ʻia i loko o ke kristal a me ka hoʻolālā o ka laser. No ka laʻana, hoʻohana kahi hoʻonohonoho laser DPSS maʻamau iā Nd:YAG ma ke ʻano he mea hoʻonui e hana i kahi laser ma 1064 nm i loko o ka spectrum infrared. Hoʻohana nui ʻia kēia ʻano laser i nā noi ʻoihana no ka ʻoki ʻana, ka hoʻoheheʻe ʻana, a me ka hōʻailona ʻana i nā mea like ʻole.

Nā Pōmaikaʻi:Ua kaulana nā lasers DPSS no ko lākou ʻano kukuna kiʻekiʻe, ka pono, a me ka hilinaʻi. ʻOi aku ka mālama pono o ko lākou ikehu ma mua o nā lasers paʻa kuʻuna i hoʻopili ʻia e nā kukui uila a hāʻawi i kahi ola hana lōʻihi ma muli o ke kūpaʻa o nā lasers diode. Hiki iā lākou ke hana i nā kukuna laser paʻa loa a pololei, he mea nui ia no nā noi kikoʻī a me ke kikoʻī kiʻekiʻe.

Nā Hoʻohana Koʻikoʻi o ka CW Diode Pumped Solid State Laser:

1.ʻOki ʻana i ka Daimana Laser:

Hoʻohana ka laser G2-A i kahi hoʻonohonoho maʻamau no ka pāpālua alapine (frequency double): ua hoʻololi ʻia kahi kukuna hoʻokomo infrared ma 1064 nm i kahi nalu ʻōmaʻomaʻo 532-nm i kona hele ʻana ma o kahi kristal nonlinear. ʻO kēia kaʻina hana, i ʻike ʻia ʻo ka pāpālua alapine (frequency doubleing) a i ʻole ka hanauna harmonic ʻelua (SHG), he ʻano hana i hoʻohana nui ʻia no ka hoʻoulu ʻana i ka mālamalama ma nā nalu pōkole.

Ma ka pāpālua ʻana i ke alapine (frequency) o ka puka ʻana o ke kukui mai kahi laser 1064-nm i hoʻokumu ʻia me ka neodymium a i ʻole ytterbium, hiki i kā mākou laser G2-A ke hana i ke kukui ʻōmaʻomaʻo ma 532 nm. He mea nui kēia ʻano hana no ka hana ʻana i nā lasers ʻōmaʻomaʻo, kahi i hoʻohana pinepine ʻia i nā noi mai nā kuhikuhi laser a hiki i nā mea hana ʻepekema a me nā ʻoihana akamai, a kaulana hoʻi ma ka Laser Diamond Cutting Area.

2. Ka Hana ʻana i nā Mea:

 Hoʻohana nui ʻia kēia mau lasers i nā hana hana mea e like me ka ʻoki ʻana, ka hoʻoheheʻe ʻana, a me ka wili ʻana i nā metala a me nā mea ʻē aʻe. ʻO ko lākou kikoʻī kiʻekiʻe e kūpono ai lākou no nā hoʻolālā paʻakikī a me nā ʻoki ʻana, ʻoi aku hoʻi i nā ʻoihana kaʻa, aerospace, a me nā ʻoihana uila.

3. Nā Noi Lapaʻau:

Ma ke kahua lapaʻau, hoʻohana ʻia nā lasers CW DPSS no nā ʻoki kino e pono ai ka pololei kiʻekiʻe, e like me nā ʻoki kino ophthalmic (e like me LASIK no ka hoʻoponopono ʻana i ka ʻike) a me nā kaʻina hana niho like ʻole. ʻO ko lākou hiki ke kuhikuhi pololei i nā ʻiʻo e lilo ai lākou i mea waiwai i nā ʻoki kino minimally invasive.

4. Noiʻi ʻEpekema:

Hoʻohana ʻia kēia mau lasers i nā ʻano noi ʻepekema like ʻole, me ka spectroscopy, ka velocimetry kiʻi ʻāpana (hoʻohana ʻia i ka dynamics fluid), a me ka microscopy scanning laser. He mea nui kā lākou hopena paʻa no nā ana pololei a me nā nānā ʻana i ka noiʻi.

5. Kelepona:

Ma ke kahua o nā kamaʻilio kelepona, hoʻohana ʻia nā lasers DPSS i nā ʻōnaehana kamaʻilio fiber optic ma muli o ko lākou hiki ke hana i kahi kukuna paʻa a kūlike, kahi mea e pono ai no ka hoʻoili ʻana i ka ʻikepili ma nā mamao lōʻihi ma o nā fiber optical.

6. Ke kaha kiʻi ʻana a me ka māka ʻana o ka laser:

ʻO ka pololei a me ka pono o nā lasers CW DPSS e kūpono ai lākou no ke kahakaha ʻana a me ka hōʻailona ʻana i nā ʻano mea like ʻole, me nā metala, nā plastics, a me nā keramika. Hoʻohana pinepine ʻia lākou no ka barcoding, ka helu serial, a me ka hoʻopilikino ʻana i nā mea.

7. Palekana a me ka palekana:

Loaʻa i kēia mau lasers nā noi i ka pale no ka hoʻolālā ʻana i ka pahuhopu, ka ʻimi ʻana i ka laulā, a me ka hoʻomālamalama infrared. He mea koʻikoʻi ko lākou hilinaʻi a me ka pololei i kēia mau wahi koʻikoʻi.

8. Hana ʻana i nā mea hana semiconductor:

I loko o ka ʻoihana semiconductor, hoʻohana ʻia nā lasers CW DPSS no nā hana e like me ka lithography, annealing, a me ka nānā ʻana i nā wafers semiconductor. He mea nui ka pololei o ka laser no ka hana ʻana i nā ʻano microscale ma nā ʻāpana semiconductor.

9. Hoʻokipa a me ka Hōʻikeʻike:

Hoʻohana ʻia lākou i ka ʻoihana hoʻokipa no nā hōʻikeʻike kukui a me nā projections, kahi e pono ai ko lākou hiki ke hana i nā kukuna kukui ʻālohilohi a paʻa.

10. ʻEnehana Olaola:

I loko o ka biotechnology, hoʻohana ʻia kēia mau lasers i nā noi e like me ka DNA sequencing a me ka cell sorting, kahi e koʻikoʻi ai ko lākou pololei a me ka hoʻopuka ikehu i kāohi ʻia.

11. Metrology:

No ke ana pololei a me ke kaulike ʻana i ka ʻenekinia a me ke kūkulu ʻana, hāʻawi nā lasers CW DPSS i ka pololei e pono ai no nā hana e like me ka pae ʻana, ke kaulike ʻana, a me ka profiling.
