Literally the opposite of resonance, antiresonance occurs when any variation in excitation frequency results in an increased response.
argon-ion laser
gas laser using ionized argon as the active medium and applying electronic excitation in order to produce the laser light
attosecond-pump attosecond-probe spectroscopy
Attosecond-pump attosecond-probe spectroscopy (APAP) is an advanced technique in ultrafast spectroscopy that allows scientists to study the dynamics of electronic processes occurring on extremely...
Auger electron spectroscopy
The energy analysis of electrons released in a secondary step following initial excitation or ionization.
