An experimental liquid crystal compensator of laser diode astigmatism is de
scribed. This compensator consists of two adaptive liquid crystal lenses. T
he compensator performs focusing of an astigmatic laser beam from infinity
to 0.5 m. Numerical and experimental results of focusing for laser diode be
am with 0.82 mu m wavelength are represented. Dispersion properties of the
compensator in 0.633-0.85 mu m region of wavelengths and transmission at 0.
82 mu m are investigated experimentally. (C) 2000 Elsevier Science B.V. All
