Brewster prism

The beam was passed through a pulse picker (4). In order to compensate pulse broadening ( chirp ) introduced by the pulse picker and to precompensate that caused by other bulky optics (lenses, polarizers etc.), the beam was passed through a group velocity dispersion compensation line (5), consisting of a pair of Brewster prisms and a mirror [20], The temporal width of the pump and probe pulses was checked with a fringe-resolved...

The reflectivity of the grating is very low at grazing incidence and the round-trip losses are therefore high. Using Brewster prisms for preexpansion of the laser beam (Fig. 5.87), the angle of incidence a at the grazing incidence...

To minimize fluctuations and drifts of the transmission maximum by air-pressure changes, the air space between the etalon plates should be as small as possible. An elegant solution is shown in Fig.6.33b where the etalon is formed by two Brewster prisms which are coated on a cathete surface and which also avoid reflection losses on the other surfaces due to the Brewster angle a. 

Fig. 1.16 The most general three-color experiment, HS harmonic separator, BS beam splitter, BBO (3-barium borate crystal, HCR hollow cube retroreflector, BP Brewster prism, CS cover slip, A/2 half wave plate, P polarizer, PM parabolic mirror, S sample, PD/LIA photodiode/lock-in amplifier. The solid lines indicate 800 nm beams, the dotted lines are the 530 nm beams, and the dashed lines are the 400 nm beams. The intervening optics between the DOE and the sample are not shown for clarity. Half-wave plates and phase plates are introduced in the straight section between the parabolic mirrors to enable the selection of any tensor element, mixed polarization state, or to perform a phase scan...
