We have demonstrated the use of phase-conjugate stimulated Brillouin scattering mirrors to produce high-quality, short-pulse KrF laser beams from angular multiplexed and regenerative amplifiers. The mirror was also shown to isolate systems optically

High thresholds were measured for KrF laser breakdown in several noble gases and air, at focused power densities up to 3 × 10 13 W/cm 2 . The dependence between the gas pressure and the breakdown threshold is in good agreement with the inverse brems

Biprisms are used as a method of wavefront division with an excimer laser source to holographically write first‐order Bragg gratings in single‐mode optical fibers. Gratings with a period of 556 nm and peak reflectivity of 62% are produced using s

Observations are presented of ∼1 μm deep periodic structures on the cladding surface of optical fibers which are simultaneously induced when recording first‐order fiber Bragg reflectors by single pulse KrF excimer laser holographic exposure.

High‐gain pulsed amplification of low intensity continuous‐wave optical signals via two‐wave mixing in a photorefractive barium titanate (BaTiO3) crystal is demonstrated. The technique relies on the nonlinear mixing between a signal field and a

The excimer laser was first operated in 1975 approximately 13 years after the invention of most other common types of lasers such as carbon dioxide (CO2), neodynium yttrium aluminium garnet (Nd:YAG), ruby, diode, dye and He-Ne.

While excimer lasers do not produce as high average powers as longer wavelength infrared lasers such as Nd: YAG and CO2, in principle their shorter wavelength allows their beams to be focused to smaller spots and obtain high intensities at the workpi

Earth mites are a complex of related species introduced into Australia in the early part of last century that cause economic damage to crops, especially canola, and to pastures. A general method of chemical control aimed at interrupting the life cycl
