Hudson, NH - Laser Components has debuted a line of laser optics with complex coatings on the front and the back for use in resonators or polarizers. The company manufactures complex coating designs upon customer request, with several combinations possible. For applications in resonators, it is suggested to use optics with a dichroic coating on the front, such as a coating that is highly reflective for 1064 nm and simultaneously allows the passage of pump light. The back can be highly or partially reflective for the same or another wavelength.
It is also possible to combine a polarization coating on one side and a mirror coating on the other side; for example, using a thin-film polarizer at 45° for 1064 nm, the back side of which is also coated for coupling in another laser wavelength. Polarization coatings on both sides of an optic are used if the polarization effect has to be increased and the highest extinction ratios are required that could not be achieved otherwise with a coating applied to just one side.
