✦ Synopsis

Laser optogalvanic (LOG) signals have been detected from a dc discharge in flowing HgBr2 vapour. Different laser lines from a 4 W Ar+ laser have been used for excitation. The signals are identified with transitions in the B-X system of this molecule and variation in the signal strength with discharge voltage and input laser power have been investigated. The LOG signal is seen to vary with laser power and the variation is wavelength dependent. An explanation for this dependence is offered.
