Ultrafast Thin Windows

Shalom EO’s ultrafast thin windows are critical ultrafast optics for transmitting femtosecond pulses with minimum losses. These thin windows are made of Fused Silica, manufactured with small thicknesses (standard 0.1mm~3mm thick). Our thin windows, available as off-the-shelf and custom windows, are offered in three standard coating configurations:

1. Uncoated blanks, the high-precision and high surface quality uncoated window substrates are excellent options for depositing other customized coatings;

2. 700-900nm AR coated, these windows are designed for 800nm Ti: Sapphire femtosecond lasers

3. 950-1100nm AR Coating, these windows are designed for 1030nm Ytterbium doped (Yb) lasers

Minimized geometric and surface profile deviation is achieved with wavefront distortion of λ/10@633nm and parallelism of <10 arcsec. Shalom EO’s ultrafast thin windows also feature a low group delay dispersion of GDD=±10fs2, which implies negligible phase distortion to the optical wavefront, leading to cleaner and more stable pulses in applications like pump-probe experiments or multiphoton imaging.
