Research Towards the Development of an Optically Pumped Cesium Dimer Laser
Metal vapor lasers are a promising candidate for high power laser systems and have been a recent area of interest. These types of lasers seem to combine all the strengths of both gas/chemical and solid state lasers without the weaknesses attributed to them. Metal vapor lasers have very efficient …

ACTIVATION OF AMMONIA, SECONDARY, AND TERTIARY AMINES BY GROUP IIA AND FIRST ROW MIDDLE AND LATE TRANSITION METAL ATOMS AND CLUSTERS
Activation of ammonia and amines occurs during metal vapor synthesis at cryogenic temperatures. The Group IIA metal atoms: magnesium, calcium, strontium, and barium, and the transition metal atoms: chromium, manganese, iron, cobalt, nickel, and zinc react with amines and ammonia. Copper metal atoms …

On the development of a low-cost lithographic interferometer
… optical source - a bulky and expensive metal-vapor laser - is replaced by a newly available, low-cost blue laser diode. Additionally, the passive alignment of a lens tube is utilized to simplify the construction of a spatial filter. The resulting custom-built interference lithography …

Development of a MeVVA based beryllium-7 plasma source
… ion source for a Malmberg-Penning trap based on Metal Vapor Vacuum Arc (MeVVA) ion source designs. Our primary intent with this MeVVA-type source is to create a confinable beryllium-7 (7-Be) plasma. 7-Be is a peculiar isotope due to its varying radioactive decay half-life in different …
