N2 - Suppression of the laser induced amplified spontaneous emission (LIASE) process between the ion-pair excited states of I2 is reported. Taking advantage of a unique feature that the amplification of radiation occurs above a certain threshold of the population inversion density, we demonstrated the notable reduction of the R(78) LIASE line intensity corresponding to the f 0g+ (3P0) (vf = 0, Jf = 79) → D 0u+ (3P2) (vD = 0, JD = 78) transition, when the lower level of the transition was intentionally pre-populated through two photon excitation by a control laser.
