功能

• A special mirror with negative wavelength dispersion.
• It can be used for dispersion compensation of femtosecond laser resonators.
• It cancels out the wavelength dispersion in the resonator by sending light back and forth multiple times between two negative dispersion mirrors.
• It is more compact than wavelength dispersion compensation by prism.
• Two types of shapes are available: flat board and cavity concave board.
• We also have a Surface Accuracy Guarantee Mirror (HTFM) that guarantees surface accuracy after coating.
• * Since it is used for 0° to 20° incidence, the dispersion may not be corrected at other incidence angles.
• * The reflectivity of the specification indicates the reflectivity of 0° incidence.
