Dispersive mirror technology for ultrafast lasers in the range 220–4500 nm

Abstract

Nowadays, dispersive mirrors are able to cover the wavelength range of 4.5 optical octaves and can be used from 220 nm up to 4500 nm. Various design approaches to dispersive mirrors in visible and near IR are briefly discussed. We consider in more detail two dispersive mirrors representing extreme cases. The first one is a mirror working in the range of 290−360 nm and providing group delay dispersion of -75 fs 2 . The second one is a mirror working in the range of 2500−4500 nm and providing +500 fs 2 of group delay dispersion.

2/3 octave Si/SiO2infrared dispersive mirrors open new horizons in ultrafast multilayer optics

“…Over the last twenty years broadband dispersive mirrors (DM) have become key optical components in modern laser systems [1][2][3][4][5]. Dispersive multilayer components provide efficient help to amplify, drive, and shape laser pulses.…”

Enhancement of the damage resistance of ultra-fast optics by novel design approaches

“…Dielectric optics, so called chirped mirrors, offer the possibility to control the electric field of the light [2]. Nowadays various chirped mirrors are commercially available covering a broad range from the visible to the near infra-red spectral range as well as the requested laser pulse parameters [3]. Ion-Beam-Sputtering (IBS) in combination with precise optical monitoring techniques is considered as one of the best concept for the deposition of high quality ultra-short pulse optics [4].…”

Improved LIDT values for dielectric dispersive compensating mirrors applying ternary composites

“…A variety of CMs from the visible (VIS) to the near infra-red spectral range (NIR) are commercially available. Typically, CMs require total film thicknesses of the stacks of several micrometers (µm) [2]. Usually, compared to conventional dielectric QWOT mirrors, the complex design structure of CMs leads to higher electrical field intensities inside the coating stack.…”
