Features
- A special mirror with negative wavelength dispersion.
- It can be ***d for dispersion compensation of femtosecond laser resonators.
- It cancels out the wavelength dispersion in the resonator by s***ing 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 ***d 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.
