    • External-cavity optically-pumped semiconductor lasers (OPS-lasers) including an OPS-structure having a mirror-structure surmounted by a surface-emitting, semiconductor multilayer (periodic) gain-structure are disclosed. The gain-structure is pumped by light from diode-lasers. The OPS-lasers can provide fundamental laser output-power of about two Watts (2.0 W) or greater. Intracavity frequency-converted arrangements of the OPS-lasers can provide harmonic laser output-power of about one-hundred milliwatts (100 mW) or greater, even at wavelengths in the ultraviolet region of the electromagnetic spectrum. These high output powers can be provided even in single axial-mode operation. Particular features of the OPS-lasers include a heat sink-assembly for cooling the OPS-structure, a folded resonator concept for providing optimum beam size at optically-nonlinear crystals used for frequency conversion, preferred selection of optically-nonlinear materials for frequency-conversion, and compound resonator designs for amplifying second harmonic-radiation for subsequent conversion to third or fourth harmonic radiation.

    • Ring and linear cavity, fiber optic laser systems are disclosed, employing non-invasive fiber optic amplification technology. A channel overlay waveguide (60) is employed for amplification of optical energy evanescently coupled to the overlay waveguide (60) from the fiber optic (30). One of two amplification methods can be employed. The first involves inducing stimulated emission with the overlay waveguide (60) and the second uses a second order, non-linear frequency conversion to down-convert a high-power, short-wavelength pump signal into the waveguide (60) to amplify the optical energy coupled thereto. Amplification of optical energy in the channel overlay waveguide (60) can be established within a single beat length of evanescent removal to evanescent return of the optical energy to the fiber optic (30). Intra-cavity elements can be employed to effect, e.g., wavelength selection, optical isolation, or modulation of the resultant optical signal propagating in the fiber optic (30).

    • An optical parametric oscillator system comprises a continuous wave, singly resonant optical parametric oscillator (OPO) arranged within the cavity of a laser used to generate the pump wave. The pump laser may have a widely tuneable laser gain medium which enables the OPO to be tuned through the tuning of its pump wave. The pump laser may generate a multiaxial mode pump wave which pumps a non-linear crystal in the OPO to generate two down converted waves; one of the generated waves is resonated in the cavity of the OPO whilst the other generated wave is prevented from resonating by being coupled out of the OPO cavity to form an output signal. A mirror arrangement common to both pump laser and OPO may be used to focus and to ensure co-axiality and co-linearity of pump and resonated waves within the non-linear material; this enhances the setting up and optimisation of the intracavity OPO. Additionally, means may be provided to efficiently couple out a fraction of the resonated wave as a useful output. This resonated output may be single frequency even in the presence of a multimode pump waved. Further, means may be provided to allow the frequencies of the two down converted waves to be independently tuned.
