Ultrafast Ti:Sapphire Laser Harmonic Beamsplitter
Ultrafast Ti:Sapphire Laser Harmonic Beamsplitter
Our ultrafast laser harmonic beamsplitter acts as a dichroic filter to separate the fundamental 800 nm wavelength from the doubled frequency of 400 nm. The beamsplitter is precision polished select grade fused silica coated with hard refractory multilayers for high damage threshold and minimum pulse dispersion.
- Separate or combine 400 nm & 800 nm Ti:Sapphire harmonics
- Minimum pulse dispersion
- Low wavefront distortion
- Hard refractory coatings for high damage threshold
- Surface quality 10-5 scratch-dig
- AR coated back surface eliminates ghosting See All Features

Features
Ti:Sapphire Laser Harmonic Beamsplitters
This harmonic beamsplitter is designed to separate harmonic wavelengths of an Ti:Sapphire laser at 45° angle of incidence. It provides high reflection (>99.5%) and transmission (>95%) at specified wavelengths. A V-coat antireflection coating is applied on the back surface to minimize the loss due to reflection. Harmonic beamsplitters are sometimes called Harmonic Separators or Dichroic Filters.
High Damage Threshold
High fluence Ti:Sapphire lasers may be used safely with this beamsplitter. Extra durable multilayer coatings are used for both the front beamsplitting surface, and the AR-coated back surface. This results in a typical damage threshold at 1064 nm of 5 MW/cm2 for CW, 5 J/cm2 for 0.1–100 nsec, 10Hz pulses. Typical damage threshold for wavelength below 532 nm is 1 MW/cm2 for CW, 1 J/cm2 for pulses.
