Laser-wakefield-accelerated electrons were used to drive an all-optical undulator source, a 5-keV betatron X-ray source and a tunable quasi-monochromatic Compton-X-ray source. Also, we present a phase-contrast tomogram of a fly obtained with the betatron beam.
This paper discusses the effect of pulse repetition rates on silicon wafer modification by four-beam laser interference. In the work, four-beam laser interference was used to pattern single crystal silicon wafers for the fabrication of dots, and different laser pulse repetition rates were applied to the process in the air. The results were obtained from 10 laser exposure pulses with the single laser...
An experimental investigation on the laser performance of an α-oriented Tm,Ho: YAIO3 crystal end-pumped by a wavelength tunable Ti:Sapphire laser is presented in this paper. Single- and dual-wavelength operations of Tm,Ho:YAIO3 lasers have been investigated in detail. Maximum output powers of 890mW at 2119nm, 836mW at 2103nm and 487mW at 2130nm for the α-oriented Tm,Ho:YAIO3 crystal have been obtained,...
Diode-pumped stable CW mode-locked laser in Yb:LuAG crystal was demonstrated. The pulse duration of 7.63 ps was achieved without any negative dispersion elements. With pump of 8 W, output power was 610 mW with repetition rate of 86 MHz.
Result of diode-pumped cw laser action of Yb:GYSO are demonstrated for the first time. The laser wavelength could be tuned from 1030 to 1089 nm, and a slope efficiency of 57% was achieved.
