A concept of a hybrid plasma source with a liquid gallium-indium propellant as a thruster for micro-satellites is proposed. Plasma source operates in two regimes: generating the laser ablation plasma and generating the plasma of low voltage vacuum arc discharge with a laser triggering. In the discharge cell of the source, the cathode is a stainless steel capillary tube filled with working liquid....
Second harmonic generation efficiency enhancement in KDP single crystals with embedded anatase nanoparticles was accomplished in comparison with nominally pure KDP crystal. The enhancement effect occurs due the self-focusing of laser pump pulses.
The use of recoil momentum from a laser ablation flare is found to be one of the promising ways for development of low-propulsion thrusters for launching of microsatellites and nanosatellites. This paper suggests using a liquid Ga-In alloy as the ablated body, instead of a solid-state one. A Nd:YAG laser with the output of 0.3 mJ and the pulse duration of 2.7 ns (full width at half maximum) was used...
The use of recoil momentum from a laser ablation flare is found to be one of promising way for development of low-propulsion thrusters (LPT) for launching of micro and nano-satellites. The present work suggests using the liquid Ga-In alloy as the ablated body instead of a solid-state one. A Nd:YAG laser with output of 0.25 mJ and pulse duration of 2.5 ns (FWHM) was used for ablation. Charge-resolved...
