产品描述

Typical applications are intracavity Q-switch hold-off polarizer or extracavity attenuator for Nd:YAG lasers.

For optimal transmission Thin Film Polarizer should be mounted in an appropriate holder for angular adjustment.

Thin Film Polarizers are used in any Q-switch Pulsed lasers both in Industrial and medical systems, where they serve as intracavity Q-switch hold-off polarizers.

They also can be used as extracavity attenuator for Nd:YAG lasers.

ADVANTAGE:

● Provide linear polarization of laser radiaton

● Rs/Tp:>99.8/95.0 % for standard thin film polarizers or Rs/Tp:>99.8/98.0 % for high transmittance thin film laser polarizers

● High damage threshold reaching 10 J/cm2

● High Extinction ratio —— 1000:1 and 500:1

● Wide working temperature (-40℃—— +60℃)
