Abstract
A frequency conversion system includes at least one source providing a first near-IR wavelength output including a gain medium for providing high power amplification, such as double clad fiber amplifier, a double clad fiber laser or a semiconductor tapered amplifier to enhance the power output level of the near-IR wavelength output. The NFM device may be a difference frequency mixing (DFM) device or an optical parametric oscillation (OPO) device. Pump powers are gain enhanced by the addition of a rare earth amplifier or oscillator, or a Ra-man/Brillouin amplifier or oscillator between the high power source and the NFM device.

A frequency conversion system comprising:
- a first source for providing a first near-IR wavelength output, said first source including a gain medium for providing high power amplification of said near IR wavelength output;
- a second source for providing a second near-IR wavelength output;
- a nonlinear frequency mixing device optical coupled to receive as an input both of said first and second wavelength outputs to produce an output having a wavelength within the mid-IR wavelength range;
- the improvement characterized in that said gain medium is selected from. the group consisting of a double clad fiber amplifier, a double clad fiber laser and a semiconductor tapered amplifier to enhance the power output level of said first near-IR wavelength output.
