Laser performance is highly dependent upon maintaining precise control over the resonator length. One way to enable such performance is by using command-driven frequency compensation.
- Adding a 0-100V piezo, to move the output coupler, can control the wavelength and power produced in lasers that have reached thermal equilibrium.
- This feature also pairs well with gratings (-G), which can minutely change the linewidths position along the gain curve, or switch between two closely spaced modes.
