Abstract
Generation of harmonics using a gas nozzle has remarkable feature in various applications. Pulses from a Ti:Sapphire laser, centered at 785 nm, in a 4 kHz train, with 25 femtoseconds and 800 μJ of maximum energy were employed to generate harmonics in an argon gas nozzle. We present the current results on the focusability of the nozzle, harmonic radiation, measurement of the influence of laser power and laser focus position on the divergence of gas nozzle. We have successfully generated 3rd, 5th and 7th harmonics in Argon at different laser powers. The results show that the harmonic signals are almost same for laser average powers over 1.0 W and variation always appears below 1.0 W. It means that there is saturation in the physical phenomenon happening inside the gas nozzle at high laser powers and the variation is non-linear below 1.0 W. These results are embedded in an effort towards x-ray generation in the water window.
