Abstract: With the help of amplification method, the small signal gain of a gas dynamic CO2 laser is measured respectively under toluene and alcohol driving conditions.The experiments show that with toluene used as fuel,the small signal gain may reach 0.62m-1,which is by far higher than that with alcohol used as fuel.In conclusion,toluene is an optimum liquid fuel for combustion driven gas dynamic CO2 laser
