Novel dichroic beam separator for frequency-doubled lasers.
A novel glass rhomb has been demonstrated for separating the residual fundamental beam from the harmonic beam in a frequency-doubled or frequency-tripled laser. This device features simple fabrication, damage resistance of uncoated glass, essentially loss-free transmittance for the harmonic beam, high (> 95%) rejection of the fundamental, mechanical and thermal stability, and high optical quality.
