A 650-J XeCl laser

High-Power Laser Systems of UV and Visible Spectral Ranges

“…Figure 9 shows the exterior view of the Photon-5 laser. The laser gas mixture is excited by a radially converging electron beam from six directions [8]. The beam is generated in a vacuum diode that contains 18 cathodes.…”

“…This laser is tested in lasing mode with the cavity formed by the Al-coated plane mirror and the laser chamber window. For the mixture Ar:Xe:HCl = 760:20:1 with a pressure of 2 atm, the radiation pulse energy amounts to 660 J at a charging voltage of 85 kV [8]. The radiation pulse FWHM is about 350 ns.…”

“…Russian institutions also develop and create the powerful excimer lasers and laser systems [4][5][6][7][8][9][10][11][12]. In particular, a KrF laser system with a Garpun output unit (Institute of Physics, Russian Academy of Sciences) has an output aperture with a size of 16 × 18 cm and one generates radiation pulses with energy of 80 J and pulse duration of 100 ns [12].…”

“…The excimer lasers developed at the High-Current Electronics Institute (HCEI), Siberian Division, Russian Academy of Sciences, generate pulses with an energy of greater than 100 J [4][5][6][8][9][10][11]. The two most powerful XeCl lasers (308 nm) with apertures of 40 [8] and 60 cm [9][10][11] generate pulses with energies of 660 J and 1.9 kJ and pulse durations of about 350 and 250 ns, respectively.…”

“…In this work, we describe three high-power excimer laser systems developed at HCEI and based on wide-aperture lasers with the output laser beam sizes 25 × 25 cm [6], 40 cm (diameter) [8], and 25 cm [29,30], respectively. The experimental results obtained on these systems are presented.…”
