Kuyerwa kwehupamhi hwemutsara weLaser
Kuyera upamhi hwemutsara weLaser Kune nzira dzakawanda dzekuyera upamhi hwemutsara welaser: 1. Kana upamhi hwemutsara welaser hwakakura (> 10 GHz, kana mamodhi akawanda achitenderera mumaresonator akawanda elaser), maspectrometer echinyakare anoshandisa diffraction gratings anogona kushandiswa pakuyera. Zvisinei, nzira iyi...Verenga Zvakawanda -
