Capabilities
- Development of a method for scaling the peak and average capability of cw and pulsed fiber sources by at least two orders of magnitude while maintaining diffraction-limited beam quality and high electrical-to-optical efficiency
- Demonstration of a peak power, pulse energy, and average power of 306 kW, 255 µJ, and 2.2 W, respectively, from a fiber amplifier seeded by a pulsed microchip laser (1064 nm wavelength, 0l8 ns pulse duration)
- Efficient generation of the 2nd, 3rd, 4th, and 5th harmonics (532 nm, 355 nm, 266 nm, and 213 nm, respectively) of a fiber amplifier seeded by a microchip laser
- Development of a side-pumping method for efficiently coupling the light from one or more pump sources (laser diodes, diode bars, or fiber-coupled sources) into a double-clad fiber
- Construction of packaged, turn-key fiber amplifiers based on our side-pumping method
- Development of a method for preparing the ends of the fiber for high power operation and to minimize optical feedback
- Development of polarization-maintaining, Yb-doped, double-clad fiber
