We have demonstrated a cryogenic Yb:YLF amplifier at 100-W average power and 10-kHz pulse repetition frequency (PRF). At 4.5 mJ, the pulses have a 2.2-nm bandwidth and have been compressed to 700 fs in duration.

We demonstrate a broadband visible-wavelength astro-comb enabled by two key technologies: dispersion-managed, fiber-optic Cherenkov radiation for green-to-red source-comb generation and complementary chirped-mirror pairs for constructing broadband Fabry-Perot filtering cavities.

We have performed ultrafast pump-probe and time-resolved photoluminescence experiments on highly excited semiconductor quantum wells in a high magnetic field, observing time-delayed suprefluorescence bursts of coherent radiation together with a sudden population drop from full inversion to zero.

We demonstrate room temperature continuous wave lasing in bottom-up photonic crystal cavities formed by patterned III-V nanopillars. Single-cell high-Q photonic crystal cavities are formed with nanopillars by selective-area epitaxy. Control of the nanopillar geometry and heterostructures allows for high-Q and large confinement factor, resulting in a low threshold power density of 75 W/cm2 at 1040 nm emission wavelength.
