TFP Thin Film Plate Polarizes are the best choice when maximum laser damage resistance is necessary. Typically, thin film polarizers are used for fluences greater than 500mJ/cm 2 , where calcite air-spaced polarizers exhibit long term tracking and cemented polarizers cannot be used at all. Applications for the TFP include usage as an intracavity Q-switch hold-off polarizer, and, in conjunction with a half wave plate, as an extracavity attenuator for an Nd:YAG laser fundamental and its harmonics. To maximize transmission, users must make a provision in their mechanical setup for the necessary angular tuning. Note that the losses at the uncoated second surface are insignificant at ¡À3 degrees from Brewster's angle. |
