Abstract:

An apparatus for generating a relatively high-power, modulated optical beam is disclosed. The apparatus comprises a first element for emitting a relatively low-power laser beam at a preselected wavelength, means for focusing the laser beam into a focused beam, a damage-resistant integrated optic modulator responsive to the focused beam for developing a modulated beam, optical means for shaping the modulated beam into a shaped modulated beam, and semiconductor means having a large active area responsive to the shaped, modulated beam for producing a relatively high-power, output modulated beam. In a first embodiment, the semiconductor means is a semiconductor amplifier which amplifies the modulated beam to produce the high-power, modulated output beam. In a second embodiment, the semiconductor means is a semiconductor amplifier with a highly-reflective, coated rear facet for reflecting the amplified focused beam back through the amplifier to produce a twice-amplified, high-power, output modulated beam which is reflected out of the apparatus by a polarizing beam-splitter in the optical means.
