Simba density uye simba density ye laser

Simba density uye simba density ye laser

Density chiitiko chemuviri isu tinoziva zvakanyanya muhupenyu hwedu hwezuva nezuva, takasimba tinobata zvakanyanya kuwanda kwezvinyorwa, formula ρ = m / kureva kuti, its, density yakaenzana nehuwandu hwakakamurwa nehoriyamu. Asi density ine simba uye density yerima reiyo laser akasiyana, apa yakakamurwa nenzvimbo kwete vhoriyamu. Simba zvakare kuonana kwedu nehuwandu hwehuwandu hwemuviri, nekuti isu tinosanganisira nzvimbo yesimba, asi iStence Yenzvimbo, iyo Simba Rakakamurwa nenzvimbo yeSpottenti yeSvomhu ndiyo density. ndiko kuti, iyo yeyunivhesiti density density iri w / m2, uye munelaser munda, nekuti iyo Laser Irradiation nzvimbo nzvimbo idiki, saka kazhinji w / cm2 inoshandiswa seyuniti. Iyo density density inobviswa kubva pane pfungwa yenguva, kusanganisa simba uye density, uye unit iri j / cm2. Kazhinji, kuenderera mberi lasers kunotsanangurwa uchishandisa simba remagetsi, nepoPUDZIDZO LASERSvanotsanangurwa vachishandisa masimba ese esimba uye simba density.

Kana iyo laser zviito, density yesimba inowanzo tarisa kana chikumbaridzo chekuparadza, kana kusimudzwa, kana zvimwe zvekuita zvinosvikwa. Chikumbaridzo ipfungwa inowanzoonekwa kana uchidzidza kufambidzana kwe lasers nenyaya. Kuti uwane kudzidza kwepfupi kupururudza (iyo inogona kutariswa seUS Stage), iyo inogona kutariswa seye NS Stage) Laser inowanzo tora pfungwa yesimba rekusimba kwesimba. Pfungwa iyi, padanho rekudyidzana, inomiririra simba rekuita pane chinangwa chenzvimbo yenzvimbo, mune imwe nzvimbo yeiyo latheni imwe chete, iyi hurukuro yakanyanya kukosha.

Iko kune zvakare chikumbaridzo cheiyo simba density yeimwe pulse jekiseni. Izvi zvakare zvinoita kuti kudzidza kwe laser-nyaya yekudyidzana zvakanyanya kuomarara. Nekudaro, midziyo yemazuva ano yekuedza inogara ichichinja, dzakasiyana siyana dzePulse simba, rinofanira kufananidzwa neyakagadziriswa. nguva, kwete nzvimbo). Nekudaro, zviri pachena kuti iyo chaiyo laser waveform inogona kunge isiri rectangular, mativi masaita, kana kunyange bhero kana gaussian, uye vamwe vakatsanangurwa nezvivakwa zveiyo laser.

Iyo pulse upfu hwacho inowanzo kupihwa nehafu-hurefu hwakapihwa neOscilloscope (yakazara peak hafu), iyo inoita kuti tiverenge kukosha kwesimba rekusimba kwesimba kubva kune simba density, iyo yakakwira. Iyo yakanyanya kukodzera hafu yekureba uye upamhi inofanira kuverengerwa neyekuwedzera, hafu kureba uye upamhi. Panga pasina kubvunza kwakadzama kuti pane paine yakakodzera mwero wekuziva. Ipapo yakawedzera neyekuparidza radial kutaura, uye wapedza.
