Optical and lasing properties of fluorophosphate glass
Neodymium-doped fluorophosphate glass is a laser material newly-developed for use in high power laser fusion systems. The low refractive index (n ∼ 1.45) and low dispersion (Abbe number ∼90) of fluorophosphate glasses give ...
The IR variability of SS433
We report here the results of a one-year monitoring programme of SS433 at IR and visual wavelengths. The most striking feature of these observations is the near constancy of the IR colours while the source's flux varies ...
IR photometry and polarimetry of 2A0311−227
The X-ray source 2A0311 − 227 has recently been identified with a star whose spectrum and polarization properties show it to be an AM Herculis type binary. These binaries are thought to consist of a synchronously rotating ...
