Abstract
We present the results of comprehensive characterization of capabilities of Crystal Scan device for measuring laser beams. (1) As small as 0.7 mm waist radius was measured for a laser beam of λ = 409 nm wavelength. The measurement lasts about 1 s with actual scan time being about 300 ms. (2) The focal waist position with accuracy better than 1% using focusing lenses of 6 mm to 50 mm focal length was determined. (3) Laser beam divergence in the range of 10-5rad to 10-2rad was measured and compared both to theoretically anticipated values as well as to the results obtained by conventional techniques. (4) We have identified the specific features of the signal received from astigmatic beams and measured the position and waist radii of both focuses. (5) The technique was successfully applied to measuring of laser beams at 1064 nm, 1341 nm and 10.6 mm wavelengths.
