In the context of inverse or parameter estimation problems we demonstrate the use of statistically based model comparison tests in several examples of practical interest. In these examples we are interested in questions related to information content of a particular given data set and whether the data will support a more complicated model to describe it. In the first example we compare fits for several...
We report a dramatic reduction in the linewidth of the carrier envelope offset frequency of a frequency comb generated by a femtosecond prism-based Cr:forsterite laser due to changes in the wavelength-dependent intracavity loss.
Carrier-envelope offset frequency (f0) dynamics of a prism-based modelocked Cr:forsterite laser are investigated in the context of a self-referenced frequency comb. Ultimately, this comb will be used in developing acetylene-filled fibers for portable frequency references.
Broadband operation is not commonly associated with nanosecond optical parametric oscillators (OPOs), and for most applications, eg. spectroscopy, narrowband operation is the desired outcome. Exceptions are found in applications involving free-space propagation, eg. active ranging, three-dimensional laser terrain-mapping and burst-illumination imaging, which require pulses with energies sufficient...
A prism-based Cr:forsterite frequency comb is stabilized, with a repetition rate of 116 MHz. The flexibility of the prism-based system aids in achieving the carrier-envelope-offset frequency (f0) beat note width of ~1.5 MHz.
