We report on a fiber amplified passively Q-switched microchip-laser delivering 85ps, 3MW pulses with 105kHz repetition rate. An all-optical synchronization technique reducing the mean pulse to pulse jitter of the microchip laser to 40ps is demonstrated for the first time. In comparison with existing setups at comparable average powers, the repetition rate is nearly on order of magnitude higher and...
We report a high power, widely-tuneable Tm-doped fiber master-oscillator power-amplifier system generating over 100 W of linearly-polarized output with a >190 nm tuning range. The output power is limited only by the available pump power.
Embedded-mirror side pumping enables fabrication of compact, efficient fiber sources using a variety of pump sources. It is the only method capable of employing the output of an unformatted diode bar. We discuss recent progress.
We present a novel approach for polarization-sensitive measurement of higher-order fiber-modes and use it to analyze mode behavior in a few-mode fiber amplifier, where we show that modes prefer to have orthogonal polarization states.
We report >20 W of average output power at 1.995 mum from a pulsed Tm-doped fiber amplifier system operating at 100 kHz. Pulse energies of >325 muJ have been generated at 50 kHz with 13 ns pulses in the same amplifier.
