THE 5-SECOND TRICK FOR DIODE LASER คือ

ยอมรับทั้งหมด จัดการความเป็นส่วนตัว— A photon’s energy decides its wavelength through the relationship E = hc/λ, exactly where h is Planck’s frequent, c could be the velocity of sunshine, and λ is wavelength. A really perfect laser would emit all photons with exactly the sa
