摘要: An all-optical modulator for modulating the output power of a high-power optical pump source is disclosed. More particularly, with the optical modulator of the invention, the output power of a CW fiber laser is modulated by a low-power laser, such as a diode laser. The modulator comprises two optical couplers which are preferably wavelength-selective and interconnected by a nonlinear single mode optical fiber with a high Raman gain. A laser system comprising a high-power pump laser, a fast signal laser with a suitable modulation depth and the optical modulator of the invention can advantageously employed in materials processing and graphics arts printing applications.
