Such output characteristics may be useful to optimize the performance of LPP EUV source. An online pulse duration adjustment within 10-40 ns was demonstrated, and a few exemplary pulse waveforms were synthesized, such as 'tophat,' 'tailspike,' and 'leadspike' shapes. In the present Letter we report on experimental results that are, to our best knowledge, the first demonstration of such functionality obtainable from nanosecond- pulse CO 2 laser technology. One of the unique features of the quantum-cascade- laser-seeded, nanosecond- pulse CO 2 laser, invented for the purpose of generation of extreme UV by laser-produced-plasma, is a robust synthesis of arbitrary pulse waveforms.

The model allows the influence of different parameters to be investigated, such as the initial electron molar fraction, on the ionization growth.

This approach has been applied to hydrogen gas regarded as a simplified model for LIBS plasmas, as a full kinetic scheme is available, including the collisional-radiative model for atoms and molecules. The results give the hint that some anomalous behaviors, such as signal enhancement by metal nanoparticles, can be attributed to this feature. The paper is focused on the role of the initial ionization on the plasma formation. The transition to breakdown of a weakly ionized gas, considering inverse bremsstrahlung, has been investigated using a state-to-state self-consistent model for gas discharges, mimicking a ns laser pulse. Modeling plasma heating by ns laser pulseĬolonna, Gianpiero Laricchiuta, Annarita Pietanza, Lucia Daniela This variant of ns-pulse 2-Î¼m SDL is well suited for applications such as high-precision light detection and ranging or ns-pulse laser materials processing after further power amplification. By means of internal total reflection in the birefringent polarizer, pulses are coupled out of the cavity sideways. For ns-pulse cavity dumping the SDL was set up with a 35-cm long cavity into which an intra-cavity Brewster-angled polarizer prism and a Pockels cell for rotation of the linear polarization were inserted.

( lasers and laser beams)Įlectro-optically cavity dumped 2 Î¼m semiconductor disk laser emitting 3 ns pulses of 30 W peak power The longest duration of a laser pulse was reached in tubes 25 and 50 mm in diameter for a pulse repetition rate of 2 â€“ 4 kHz. This technique permits limiting the excitation of the working levels at the initial stage of the discharge development to lengthen the inversion lifetime. To lengthen the pulse, the discharge current was limited using a compound switch comprising a pulsed hydrogen thyratron and a tacitron. We report the development of a copper bromide vapour laser with an output pulse duration of up to 320 ns.
