UV Harmonic Separators
IBS Coated UV Harmonic Separators Designed for High Power Femtosecond and Picosecond Lasers
Harmonic separators with high transmission are dichroic beamsplitters that reflect one wavelength and transmit the other.
The main advantages of a UV harmonic separator are high transmission T>98%@515 nm + T>99%@1030 nm and high LIDT (Laser Induced Damaged Threshold) at reflected 343 nm p-polarized wavelength >0.3 J/cm2 at 200 fs, 100 Hz or >0.7 J/cm2 at 10 ps, 50 kHz.
The rear surface of harmonic separators is antireflection coated to minimize back reflections.
