MPE (qhov ua tau tshaj plaws) yuav muab faib ua ib txog plaub theem. Cov khoom lag luam laser yuav tsum xa cov ntawv ceeb toom ntawm chav kawm II, III thiab IV rau cov khoom lag luam laser.
Chav kawm I: cov zis hluav taws xob qis (lub zog qis dua 0.4mw), nyob rau ib qho xwm txheej twg, nws yuav tsis tshaj MPE tus nqi rau qhov muag thiab tawv nqaij, txawm tias tom qab tsom mus los ntawm lub kho qhov muag. Nws tuaj yeem lav qhov kev pov hwm ntawm tus qauv tsis muaj kev kho tshwj xeeb. Kev siv raug xws li laser pointer, CD player, khoom siv CD-ROM, cov khoom ntsuas geological thiab cov cuab yeej ntsuas tsom, ntsuas sib kis tau luv, thiab lwm yam (thov thaum lub teeb sib kis)
Chav Kawm II: tso tawm qis pom laser (Lub Hwj Chim: 0.4mw-1mw), lub sijhawm cov tshuaj tiv thaiv ntawm lub qhov muag kaw yog 0.25s, thiab cov kis tau suav nrog lub sijhawm no tsis tuaj yeem tshaj MPE tus nqi. Feem ntau, lub laser hauv qab 1MW yuav ua rau kiv taub hau thiab tsis paub qhov tseeb. Nws tuaj yeem' t tau hais tias nws muaj kev nyab xeeb los siv qhov muag kaw rau kev saib xyuas. Tsis txhob ncaj qha rau hauv qhov nqaj, thiab tsis pom ncaj qha rau lwm tus neeg' s ob lub qhov muag nrog chav kawm qib II laser, kom tiv thaiv chav kawm laser II kom pom los ntawm saib cov cuab yeej. Kev siv xws li kev ua qauv qhia hauv chav kawm, laser pointer, tsom cov khoom siv thiab rangefinder.
Chav Kawm III: nruab nrab tso zis laser, yog hais tias cov nqaj ncaj qha mus rau hauv lub qhov muag, yuav ua rau kev puas tsuaj, raws li qee qhov kev tuav pov hwm, txuas ntxiv mus rau hauv IIIa thiab IIIB. Chav Kawm IIIA yog pom lub teeb nruam laser, thiab cov zis yog 1-5MW laser nqaj. Lub zog ceev ntawm cov nqaj yuav tsum tsis pub tshaj 25W / MM, kom tiv thaiv kev siv cov khoom siv sib tshooj los saib xyuas IIIA laser, uas yuav ua rau muaj kev phom sij ntxiv. IIIA muaj ntau qhov zoo sib xws nrog chav kawm II, xws li laser pointer, laser scanner, thiab lwm yam Chav Kawm III B txuas ntxiv laser ntawm 5-500 MW yog txaus ntshai thaum saib ncaj qha rau hauv kab teeb ci. Txawm li cas los xij, qhov tsawg kawg daim ntawv teev kev cuam tshuam yog 13 cm, thiab lub sijhawm siab tshaj plaws teeb pom kev zoo tsawg dua 10 vib nas this. Kev siv ntawm IIIB laser, xws li tsom teeb tsom thiab kev lom zem teeb pom kev zoo.
Chav Kawm IV: cov zis tso zis txuas mus ntxiv laser (ntau dua 500 MW), siab dua qib theem thib peb, muaj kev pheej hmoo ntawm hluav taws, kev hloov siab tsis nco qab kuj txaus ntshai. Cov kev siv raug suav nrog kev phais, kev qhia, txiav, vuam thiab micromachining. Qeb 1 tseem ceeb rau laser pointer, CD player, CD-ROM cov cuab yeej siv, cov khoom ntsuas geological thiab kev ntsuas ntsuas lub ntsuas. (thov thaum lub teeb ci nthuav tawm) vim tias lub zog qis dua 0.4mw. Yog li nws' s tsis muaj teeb meem rau lub qhov muag. Txawm li cas los xij, vim tias qhov luv nruab nrab ntawm ob lub lasers tsis pub tshaj 1 meter, muaj lwm lub lasers hauv tshuab, uas yog qib 1, tab sis lawv tsis yog qhov teeb meem rau ntsuas ntsuas.
