1. An apparatus comprising:

  • an optical transmitter component configured for use in a long-range optical measuring device, the component including;

    a signal laser that emits a laser signal;

    a first photonic-crystal optical device operatively coupled to receive the signal laser signal, the photonic-crystal optical amplifier device including a signal waveguide that has a diameter of at least 40 microns and maintains a single transverse mode, andat least one wavelength-conversion optical medium operable to receive high-peak-power input radiation having a first wavelength from the signal waveguide of the first photonic-crystal device and to generate radiation having a peak power of at least about 100 kW and a second wavelength that is shorter than 400 nm through wavelength conversion.
