Broadband beam sampler

The broadband beam sampler splits or samples 1-10% of the beam energy by Fresnel reflection from a single uncoated surface. This enables beam monitoring with minimal loss of transmit power. The back surface of the optical element was slightly wedge-shaped and coated with an antireflection film to prevent ghosting.
