Summary on Grant Application Form |
|
The proposed programme will develop wavelength diverse sources through the combination of 2 important technologies: the MOPFA and periodically poled nonlinear crystals. The operational power levels of the pump sources are unique and provide an extensive array of pump wavelengths, pulse parameters and power levels not available elsewhere.In c.w. operation, cascaded, resonant raman, seeded fibre schemes will be used to generate second harmonic generation from 500 nm to 700 nm in periodically poled crystals with output average powers in the 1-2W range, in ultracompact configurations and with exceptionally high wall plug efficiencies. Harmonic conversion efficiencies will be further enhanced through direct modulation of the seed signals to the MOPFA configurations. The diversity of wavelengths and power levels will permit investigations of the damage dependence of the periodically poled nonlinear crystals on these parameters.The same sources will also be employed for the pumping of singly resonant optical parametric oscillators to provide widely tunable, 1-5 micron, compact sourses with widely selectable output pulse parameters. The combination will provide a inique, diverse optical source for a large number of opto-electronic applications.
