Enhanced Listing – Broadband and Wide-Angle Laser Mirrors

18 Aug 2022

As well as Knight Optical’s Low GDD Ultrafast Laser Mirrors, we can also provide broadband and wide-angle alternatives to cover more of a range of applications.

Our Wide-Angle Laser Mirrors optimised for the fundamental and second harmonic (SHG) emissions of Ytterbium (Yb) doped lasers including diode-pumped solid-state (DPSS) and fiber lasers, and therefore have a design wavelength of either 515nm or 1030nm. They exhibit > 99.9% reflection when used between 0 to 45°.

The Broadband Laser Mirrors work from 700-900nm ideal for applications using a Ti:Sapphire laser, again demonstrating > 99.9% reflection within this wavelength range.

Their key features include:

Ion beam sputtered (IBS) coating which is compact and durable.
Reflection > 99.9% within their design wavelength range.
Broadband laser mirrors work at 45°
Exhibit minimal group delay dispersion (GDD) to prevent pulse broadening
High laser induced damage threshold (LIDT)
Precision flatness and surface quality to minimise laser scattering

Both types of laser mirror are available as 12.7mm, 25.4mm, and 50.8mm diameters, and have the following specifications:
