Multiple-Prism Beam Compressors
Multiple-prism beam compressors designed either in additive or compensating dispersive configuration. These are geometrical compressors that reduce the cross section of a propagating laser beam (not to be confused with prismatic pulse compresors). Their function is described by considering the propagation from right to left in the figure below. Input parameters include: laser wavelength, input aperture, beam compression factor, transmission efficiency, required physical length of the multiple-prism array. Option 1: design only. Option 2: design plus US made multiple-prism array. Representative multiple-prism beam compressor specifications are available in PDF form. Specialized designs for the ultraviolet and the infrared regions of the spectrum are also available on request.
Note: the principles of the multiple-prism beam compressors mentioned here are described in F. J. Duarte, Quantum Optics for Engineers (CRC, New York, 2014) (see Chapter 6). Explicit multiple-prism compressors are depicted in Fig. 6.6. Geometrical beam compression is achieved via the reverse, or return, beam pass in a conventional multiple-prism beam expander. Numerous configurations of multiple-prism beam compressors are given in F. J. Duarte, Multiple-prism dispersion equations for positive and negative refraction, Appl. Phys. B 82, 35-38 (2006).
