摘要： An optical system (31) with an input optical source (33) for projecting an input beam along an optical axis and an optical element (37, 43) which creates a cone refracted beam (41) from the input beam (35) then reconstructs the input beam (49). The optical element may comprise a first cone refractive element (37) which creates a cone refracted beam and reconstructs the beam using a reconstructing optical element (43) to apply a phase shift to the cone refracted beam. The optical system may be used to form a laser or a gain medium for a laser.

摘要： The generation of terahertz electromagnetic radiation, using a laser which is incident upon an electrically biased photoconductor and an antenna. The device has a layered structure comprising a semiconductor substrate below a wetting layer (55) epitaxially grown on the substrate, barrier layers (57) are positioned above and below a quantum dot layer (59). A contact layer (60) is provided with a contact (61) which couples the quantum dot structure to a voltage source (63). The reduction of the carrier lifetime in a conducting state, allied to its high carrier mobility that is possibly comparable to that of bulk GaAs can provide fast photoconductive devices and produce sources of terahertz radiation.

摘要： A mode locked semiconductor disk laser with an output beam having an ultra-short pulse length which provides the incident beam to a non linear microscope. The wavelength of the beam is at or near the action cross section maximum absorption wavelength for creating two photon excited fluorescence of a fluorescent biological marker in a sample. Semiconductor disk lasers combine excellent beam quality and output power, stability while maintaining simplicity and easiness of operation. In addition, these types of lasers are ideally suited for mass production as they are built in wafer-scale technology enabling a high level of integration. Importantly this non expensive, turn-key, compact laser system could be used as a platform to develop portable non-linear bio-imaging devices for clinical studies, facilitating its wide-spread adoption in “real-life” applications.
