Pulsed lasers can be modulated on/off. CW lasers with the current modulation option can be current modulated from 10 Hz to 2.5 MHz, which modulates the power but also translates into 3.8 GHz pp of frequency modulation. The PZT feature of the CW-MHF laser enables independent wavelength modulation of up to 1 cm-1 at up to 100 Hz.
