Abstract A KrF discharge laser (248 nm) has been used to laser trigger, by volume preionization, a spark gap switch (38–65 kV, >10 kA, 100 ns pulse duration) filled with 20 different gas mixtures using various combinations of air, Ar, CH4, H2, He, N2 SF6, and Xe. A pulsed lase...
The properties of an electron beam trapped and accelerated in a laser wakefield have been investigated. Plastic scintillating fibers were employed together with position sensitive photomultiplier tubes (PMT) and a series of dipole electro-magnets to study the beam. The measured momentum spectrum peaks ...

Wavelength tuning characteristics of a Fabry-Perot semiconductor laser with an external short cavity are analyzed, in which the oscillation wavelength can be changed by slightly altering the external cavity length. Analysis is based on rate equations for an optical power and carrier density. It is ...
We have investigated the output power characteristics of a laser-diode end-pumped quasi-threelevel (4F3/2-4 I9/2) 914 nm-Nd:YVO4 laser by using a simple plano-concave cavity. For the effective quasi-three-level transition, we analyzed the cavity with a thermal lens in the laser medium ...

A study is presented of the gain characteristics of a stripe-geometry GaAs homostructure laser, the positive feedback of which is suppressed by locating the active region axis at an angle to end shears of the crystal. Radiation from a conventional stripe-geometry homostructure laser emitting under...
do not need two mirrors on both sidesof the active zone to form optical cavities. Rather, diffraction on the active region serves as a wavelength select component and provides feedback through one mirror.Because of its high output power and stability, this laser is primarily utilized forhigh ...
