Ētahi Pātai Whai Hua mō te Erbium Glass Laser

1. He aha te rerekētanga i waenga i te whānui o te pā (ns) me te whānui o te pā (ms)?

Ko te rerekētanga i waenga i te whānui o te pā (ns) me te whānui o te pā (ms) koia tēnei: ​​ko te ns e pā ana ki te roanga o te pā mārama, ko te ms e pā ana ki te roanga o te pā hiko i te wā e tukuna ana te hiko.

2. Me whakarato e te taraiwa taiaho he pātere poto o te 3-6ns, ka taea rānei e te kōwae te whakahaere i a ia anō?

Kāore e hiahiatia he kōwae whakarerekētanga o waho; mena he pāoro kei roto i te awhe ms, ka taea e te kōwae te whakaputa i tētahi pāoro mārama ns anake.

3. Ka taea te whakaroa i te awhe pāmahana mahi ki te 85°C?

Kāore e taea e te awhe pāmahana te eke ki te 85°C; ko te pāmahana mōrahi kua whakamatautauria e mātou ko -40°C ki te 70°C.

4. He kōhao kei muri i te karu whakaata kua kī tonu i te hauota, i ētahi atu matū rānei, hei ārai i te kohu e puta mai ana i roto i ngā pāmahana tino iti?

Kua hangaia te pūnaha mō te whakamahi i ngā pāmahana iti iho i te -40°C me runga ake, ā, e kore te karāhe whakawhanui hihi, e mahi ana hei matapihi whatu, e kohu. Kua hiritia te kōhao, ā, kua whakakīia ā mātou hua ki te hauota i muri i te karāhe, kia mau ai te karāhe i roto i te taiao hau kore mahi, kia noho ai te karāhe i roto i te āhuarangi ma.

5. He aha te mea e whakamahia ana hei whakawhiti i te aho?

I whakamahia e mātou te karāhe Er-Yb hei rauemi hohe.

6. Me pēhea te pamu i te reo hiko?

I whakamahia he haruru iti i runga i te taiaho diode kua whakakīia ki raro hei papu i te reo hohe ki te taha roa.

7. Me pēhea te hanganga o te kōhao taiaho?

I hangaia te kōhao taiaho e te karāhe Er-Yb kua pania me te hononga putanga.

8. Me pēhea te whakatutuki i te rerekētanga 0.5 mrad? Ka taea e koe te mahi i te iti iho?

Ka taea e te pūnaha whakawhanui me te whakakotahi hihi kua whakauruhia ki roto i te taputapu taiaho te whakawhāiti i te koki rerekētanga o te hihi ki te 0.5-0.6 mrad noa iho.

9. Ko ā mātou āwangawanga matua e pā ana ki ngā wā piki me ngā wā heke, nā te mea he poto rawa te pā o te pūhiko taiaho. E tohu ana te whakatakotoranga i te whakaritenga o te 2V/7A. E tohu ana tēnei me tuku e te pūtake hiko ēnei uara i roto i te 3-6ns, kāore rānei he papu utu kua whakauruhia ki roto i te kōwae?

E whakaahua ana te 3-6n i te roa o te pā o te hihi whakaputa taiaho, kaua i te roa o te pūhiko hiko o waho. Me kī taurangi noa te pūhiko hiko o waho:

① Te whakaurunga o te tohu ngaru tapawhā;

② Ko te roanga o te tohu ngaru tapawhā kei roto i ngā mirihekona.

10. He aha ngā āhuatanga e pā ana ki te pumau o te pūngao?

Ko te pumau o te pūngao e pā ana ki te kaha o te taiaho ki te pupuri i te pūngao hihi putanga ōrite mō ngā wā roa e mahi ana. Ko ngā āhuatanga e pā ana ki te pumau o te pūngao ko:

① Ngā rerekētanga pāmahana

② Ngā piki me ngā heke o te pūtake hiko taiaho

③ Te koroheketanga me te poke o ngā wāhanga whatu

④ Te pumau o te pūtake papu

11. He aha te TIA?

Ko te TIA he whakarāpopototanga mō te "Transimpedance Amplifier," he whakakaha e huri ana i ngā tohu iahiko hei tohu ngaohiko. Ko te TIA te mea nui hei whakakaha i ngā tohu iahiko ngoikore e whakaputaina ana e ngā photodiode hei tukatuka me te tātari atu. I roto i ngā pūnaha taiaho, ka whakamahia tahitia me te taiaho urupare hei whakau i te mana whakaputa taiaho.

12. Hanganga me te kaupapa o te taiaho karāhe erbium
