He aha ka laser cryogenic
He aha ka "laser cryogenic"? ʻO ka ʻoiaʻiʻo, he laser ia e pono ai ka hana haʻahaʻa haʻahaʻa ma ka medium gain. ʻAʻole hou ka manaʻo o nā lasers e hana ana ma nā mahana haʻahaʻa: ʻo ka lua o ka laser ma ka mōʻaukala he cryogenic. I ka wā mua, ua paʻakikī ke kumumanaʻo e hoʻokō i ka hana mahana lumi, a ...E heluhelu hou aku -
