Summary
The B.I Stepanov Institute of Physics offers consumers a radially or azimuthally polarized conical light beam generator under a manufacturing agreement and is looking for partners to conclude a distribution services agreement.
Description
Radially or azimuthally polarized conical light beam generator is a system consisting of a linearly-polarized laser radiation source and a unit converting this radiation into radially or azimuthally polarized conical light beam, namely, into Bessel or ring light beam. The basic optical layout of the device is shown on the figure.

Application:
The device can be manufactured by the order of the interested organizations to obtain radially or azimuthally polarized light beams with the aim to use them in profilometry and precision laser processing of materials. The axial symmetry of the electric vector in the generated light beam allows one to have uniform azimuthal coordinate conditions in terms of the polarization
of the incident to the studied surface radiation. Radially polarized laser beam focusing will allow one to form conical light beams with low-diameter intensity maxima due to the longitudinal component of the electric field.

Technical parameters:
- laser radiation wavelength is determined by the wavelength of the laser radiation source used in the generator in the range of 400÷1100 nm;
- operation mode is pulsed or continuous, corresponds to the operation mode of the laser radiation source used in the generator;
- aperture of the converted laser radiation is 1÷10 mm;
- power of the converted laser radiation does not exceed the threshold - power of the converted laser radiation does not exceed the threshold of the beam strength of the biaxial crystal used in the device with relation to the axial maximum intensity of the output beam inside the crystal;
- conversion factor: when using the illumination of the surfaces of the optical elements included in the device - up to 90%, with no illumination - up to 65%;
- longitudinal size (length) of the device equals to the sum of the length of the laser radiation source used in the device and - longitudinal size (length) of the device equals to the sum of the length of the laser radiation source used in the device and the length of the Converter, and is up to 50 cm;
- transverse sizes (width and height) of the device are not less than the corresponding dimensions of the laser radiation source.
