    摘要： The present invention describes a self mode locking laser and a method for self mode locking a laser. The laser (1) comprises a resonator terminated by first (3) and second (4) mirrors and folded by a third mirror (5). The third mirror comprises a single distributed Bragg reflector (17) upon which is mounted a multilayer semiconductor gain medium (18) and which includes at least one quantum well layer and an optical Kerr lensing layer (22). Self mode locking may be achieved by configuring the laser resonator such that the lensing effect of the Kerr lensing layer acts to reduce an astigmatism deliberately introduced to the cavity mode. The self mode locking of the laser may be further enhanced by selecting the length of the resonator such that a round trip time of a cavity mode is matched with an upper-state lifetime of one or more semiconductor carriers located within the gain medium.

    摘要： A self mode locking laser and corresponding method is described. The laser comprises a resonator (2) terminated by first (3) and second (4) mirrors and folded by a third mirror (5). The third mirror comprises a reflector (15) surmounted by a multilayer semiconductor gain medium (16) that includes at least one quantum well layer and an optical Kerr lensing layer (20). A perturbator is also included that provides a means to induce a perturbation on an intensity of one or more cavity modes of the resonator. The pertubator is employed to induce a small perturbation on the intensity of the cavity modes of the resonator which is sufficient for the optical Kerr lensing layer to induce mode locking on the output field. The second mirror (4) comprises an intensity saturable mirror that provides a means for reducing the pulse widths of the generated output field e.g. to around 100 fs. A diamond heat spreader (20) is attached to the top of the half VCSEL gain medium (13) for improved cooling as well as representing the Kerr medium. Further folding mirrors (6-8) may be inserted to adjust the degree of astigmatism to be compensated for by the Kerr effect used for mode-locking.

    摘要： An optical amplifier is described. The optical amplifier (1) comprises a semiconductor disk gain medium (2) including at least one quantum well layer (9) and a pump field source (17) for generating an optical pump field (3) for the semiconductor disk gain medium. The optical amplifier acts to generate an output optical field (5) from an input optical field (4) received by the optical amplifier and arranged to be incident upon the semiconductor disk gain medium. Employing a semiconductor disk gain medium within the optical amplifier allows it to be optically pumped and thus provided for increased stability and beam quality of the output optical field while allowing for the design of optical amplifiers which can operate across a broad range of wavelengths. The optical amplifier may be employed with continuous wave or pulsed input optical fields.
