abstract = {Extreme ultraviolet (EUV) light generation by hybrid
laser-assisted vacuum arc discharge plasmas, utilizing
Sn-coated rotating-disc-electrodes, was investigated. The
discharge was initiated by localized ablation of the liquid
tin coating of the cathode disc by a laser pulse. The laser
pulse, at 1064 nm, was generated by Nd:YAG lasers with
variable energy from 1 to 100 mJ per pulse. The impact of
shortening the laser pulse from 7 ns to 170 ps on the EUV
generation has been investigated in detail. The use of ps
pulses resulted in an increase in emission of EUV radiation.
With a fixed discharge energy of ~4 J, the EUV conversion
efficiency tends to plateau at $~2.4 ± 0.25\%$
for the ps laser pulses, while for the ns pulses, it
saturates at $~1.7 ± 0.3\%.$ Under similar
discharge and laser energy conditions, operating the EUV
source with the ps-triggering resulted also in narrower
spectral profiles of the emission in comparison to
ns-triggering. The results indicate an advantage in using
ps-triggering in laser-assisted discharges to produce
brighter plasmas required for applications such as
metrology.},
