beam parameter utpaad

lazer vigyaan mein, beam parameter utpaad (bee. pee. pee.) ack lazer beam key vichalan konn (aadhaa konn) aur beam kii trijya key sankeern bindu (beam cummer) kaa utpaad haye. bee. pee. pee. ack lazer beam kii gunavatta kii matra nirdhaarit kartaa haye, aur yeh ack chhote seey sthaan parr kitni achchi tarah seey kendrit kiya jaa sakata haye.
ack gausi kiran mein sabse cumm sambhav bpp, sootra _ 1 hotaa haye, jahan sootra _ 2 prakaash kii tarang dairdhya haye. ack hii tarang dairdhya parr ack aadarsh gausi kiran key vaastavik kiran key bee. pee. pee. key anupaat koo aim. 2 ("aim. varg") kahaa jaataa haye. yeh parameter kiran kii gunavatta kaa ack tarang dairdhya-swatantra maap haye.
kaee anuprayogon key liye ack kiran kii gunavatta mahatvapurna haye. fiber-optic sanchaar mein ekal-mode optical fiber key liye yugman key liye 1 key karib aim2 key saath beam kii aavashyakta hoti haye. lazer machine kii dukaanen apane lazer key aim2 parameter key baare mein bahut parwah karati hain kyonki beam ack aise kshetra parr dhyaan kendrit karenge joe samaan tarang dairdhya aur dee4sc cummer kii chaudaai key saath ack gausian beam kii tulanaa mein aim4 gunaa badaa haye; dusare shabdon mein, pravaah paimaane 1/aim4 key roop mein. angoothe kaa niyam yeh haye kii lazer shakti badhane key saath aim2 badhata haye. lazer laabh madhyam mein thermal lancing key kaaran utkrisht beam gunavatta aur uchch ausat shakti (100 doubleu seey kws) praapt karna mushkil haye.
maap.
ack kiran kii chaudaai koo paribhaashit karane key kaee tareeke hain. beam parameter utpaad aur m2 koo maapate samay, beam kii cummer kii trijya aur door key kshetra mein vichalan donon koo nirdhaarit karane key liye beam kii d4σ yaa "dusare kshan" chaudaai kaa upayog kiya jaataa haye.
bee. pee. pee. koo uchch optical gunavatta aur gyaat fokal lambai key lens key saath dhyaan kendrit karane key baad beam key bheetar kaee sthitiyon mein ack sarani detector yaa scanning-slitt profiler koo rakhkar aasaani seey maapa jaa sakata haye. bee. pee. pee. aur aim. 2 koo thheek seey praapt karane key liye nimnalikhit charanon kaa paalan kiya jaanaa chaahieh
siddhant roop mein, koee bhee cummer key vyaas koo praapt karane key liye cummer parr ack hii maap kaa upayog curr sakata haye, door key kshetra mein ack hii maap seey vichalan praapt curr sakata haye, aur phir bee. pee. pee. kii ganana karane key liye inca upayog curr sakata haye. haalaanki, uparokt prakriya abhyaas mein adhik sateek parinam detee haye.
uchch-shakti vaale lazer, jaise kii lazer welding aur cutting mein upayog kiye jaane vaale lazer koo aam taur parr beam kaa namuna lene key liye beamsplitter kaa upayog karke maapa jaataa haye. namoone kii kiran kii teevrata bahut cumm hoti haye aur ise scanning-slitt yaa chaku-kinare vaale profiler dwara maapa jaa sakata haye. lazer welding aur cutting sanchaalan mein achchi beam gunavatta bahut mahatvapurna haye.
