Kekahi mau nīnau e pili ana i nā laser body clenk

1. He aha kaʻokoʻa ma waena o ka laulā pulse (NS) a me ka laulā pulse

ʻO kaʻokoʻa ma waena o ka laulā pulse (ns) a me ka laulā pulse (ms) penei

2. Pono ka mea hoʻokele kaʻa e hāʻawi i kahi pōkole pōkole pōkole o 3-6ns, a iʻole e hiki ai i ka module i luna?

ʻAʻole koiʻia ka modula modula E like me ka lōʻihi o ka pulse i loko o ka ms rate, hiki i ka module ke hana i kahi pulse pulse i kāna iho.

3

ʻAʻole hiki ke hiki i ka māhele honua ke hiki iā 85 ° C; ʻO ke kiʻekiʻe kiʻekiʻe ua ho'āʻo mākou he mau -40 ° C a 70 ° C.

4. Aia paha kahi lua ma hope o nā lens i piha me nā nitrogen a iʻole nā ​​mea'ē aʻe e hōʻoia ai i loko o nāʻano haʻahaʻa loa?

Hoʻolālā ka'ōnaehana no ka hoʻohanaʻana i nā mahana e like me -40 Ua hoʻopaʻaʻia ka lua, aʻo kā mākou huahana e hoʻopiha ana i nā lens, e hōʻoia ana i nā lens i loko o kahi aniani i loko o kahi aniani i loko o kahi aniani.

5. He aha keʻano o ka hanaʻana?

Ua hoʻohana mākou i nā aniani er-yb e like me keʻano ikaika.

6

ʻO kahi chirp compact ma luna o ka submulant i paʻiʻiaʻo Diodeʻo Diode Laser i uesd i ka lōʻihi lōʻihi i ka wikiwiki o keʻano ikaika.

7

Ua hoʻokumuʻia ka lua pele e kahi aniani er-yb a me kahi mea hoʻohilahila.

8 Hiki iāʻoe ke hana liʻiliʻi?

ʻO ka hoʻonuiʻiaʻana o ka papa inoaʻo Beam-expaninsion a me keʻano o ka'ōnaehana Laser ma keʻano he kuleana o ka Beivergencture o ka Beivergencture e like me ka haʻahaʻa o 0.5-0.6mrad.

9. E pili i kā mākou mau mea nui mua e pili ana i ka piʻi a hāʻule i nā manawa, hāʻawi i ka puser pōkole pōkole loa. ʻO ka mea kiko'ī e hōʻike ana i kahi koi o 2v / 7a. Pono kēia i kēia mea e pono ai ka hāʻawiʻana o ka mana i kēia mau kumuwaiwai i loko o 3-6ns, a iʻole he mea hoʻopiʻi i hoʻohuiʻia i loko o ka pahu?

ʻO ka 3-6n e wehewehe ana i ka lōʻihi o ka pulse o ka pā o ka laser i loko o ka bear champ ma mua o ka lōʻihi o keʻano o ka mana o waho. Pono ka hāʻawiʻana o ka mana o waho i ka gurantee:

① intput o ka hōʻailona hōʻailona wāwae wāwae;

②ʻO ka lōʻihi o ka hōʻailona o ka hōʻailona square i loko o Milliseconds.

10. He aha nā mea e hoʻopilikia ai i ka ikaika o ka ikehu?

E pili ana i ka ikaika o ka ikehu i ka hiki ke mālama i ka laser e mālama i ka ikaika o ka nui o ka ikaika. ʻO nā mea e pili ana i nā mea hoʻoikaika ikaika e komo ai:

①

② folctucations i loko o ka lako o ka mana o Laser

③ Aging a me ka lukuʻana i nā'āpana optical

④ Ka nui o ke kumu ple

11. He aha ka Thia?

Ke kū neiʻo Tia no ka "Transimped Amphifier,"ʻo ia kahi Amplifier e hoʻohuli ai i nā hōʻailona o kēia manawa i nā hōʻailona Voltage. Ua hoʻohana nuiʻiaʻo TIA i nā hōʻailona i nā hōʻailona i hala i hala i nā kiʻi i hanaʻia e nā kiʻi kiʻi hou aku no ka hoʻoili houʻana a me ka loiloi. Ma nā'ōnaehana Laser, ua hoʻohana pinepineʻia ia me kahi diode remoback e hoʻokūkū i ka mana o ka laser.

12.ʻO keʻano a me ke kumu a me ke kumu o kahi laser aniani laser

E like me ka hōʻikeʻana ma ke kiʻi ma lalo
