A TE duolaser providing simultaneous lasing on CO2and N2O transitions

Simultaneous laser action on CO
2
and N
2
O transitions has been achieved in a helical resistor-pin-type transversely excited (TE) laser. The laser emits typically a power of 10-100 kW in a 700-ns-long pulse which consists basically of two overlapping pulses, the peaks of which do not coincide, and which can be associated with the CO
2
and N
2
O emission, respectively. The conditions of optimal operation are described and the effects of some parameter changes are indicated.
