Chirped Mirrors and Highly-Dispersive Mirrors

Chirped Mirrors are dispersion compensating mirrors with a chirped laser mirror coating that compensates for the pulse broadening that ultrafast laser pulses experience as they travel through optical mediums. Highly-Dispersive Mirrors (HDM) are coated with a highly dispersive chirped multilayer coating and are used for pulse compression or intracavity dispersion compensation. Chirped or Highly-Dispersive Mirrors can be designed with low angles of incidence (AOI) to maximize the number of reflections between two paired mirrors or with larger angles for general beam steering. These ultrafast mirrors can be used in place of prism or grating compressors and offer the benefits of creating more compact, alignment-insensitive systems, which compensate for GDD as well as third-order and high-order dispersion, enabling shorter output pulses.

Edmund Optics offers a growing line of Chirped Mirrors and Highly-Dispersive Mirrors for use with femtosecond laser sources, including Ti:sapphire, Yb:doped fiber, thulium (Tm), and Holmium (Ho). These mirrors are available with low AOIs for ultrafast pulse compression, or with larger AOIs, such as 45o, for compression of ultrafast pulses during beam transport. Please contact us if your application requires a custom Chirped Mirror or Highly-Dispersive Mirror.
