Optically pumped semiconductor lasers (OPSL) have been replacing legacy gas lasers and solid state lasers for over a decade, due to their superior properties such as compactness, high efficiency, low noise, wavelength scalability, and power scalabili

We have demonstrated a novel Mach-Zehnder soft x-ray interferometer that uses diffraction gratings as beam splitters. The interferometer was used together with a 46.9nm tabletop soft x-ray laser, to map the evolution of the electron density distribut

We have performed systematic measurements and numerical modeling of the divergence and exit beam size of a 46.9 nm Ne-like Ar capillary discharge pumped soft-x-ray amplifier. Two-dimensional near-field and far-field measurements were obtained over a

We have measured the variation of the spatial coherence with plasma column length in a saturated table-top 46.9-nm Ne-like Ar capillary discharge soft x-ray amplifier for lengths up to 16.4 cm. The measurements, which are in good agreement with time

Starting with the discovery of x‐ray lasers in 1984, laser‐created plasmas remained for almost a decade, the only medium in which large amplification of soft‐x‐ray radiation could be obtained. In this paper the recent first demonstration of l

Gain length products up to gl/spl ap/14 for the J=0-1 line of Ne-like Ar at 46.9 nm have been achieved in 15-cm-long plasma columns generated by a fast capillary discharge. Amplification in plasma columns up to 20 cm in length was investigated. The l

We report modulation saturation and time response measurements on InGaAs-InGaP MQW modulators. The measurements yield a saturation intensity of (3.7/spl plusmn/0.1) kW/cm/sup 2/ for a 0-10 V swing and switching times between 10 and 90 ns, depending o

We present laser results of OPS structures based on highly strained InGaAs quantum wells emitting at 1178nm and frequency doubled to produce high power, high beam quality laser radiation at 589nm. The laser architecture is the same as in our commerci

The ambipolar diffusion coefficient and carrier recombination lifetime in InGaP/InAlP multiple quantum wells and InGaP epitaxial layers grown by gas source molecular beam epitaxy have been determined by measuring the diffraction efficiency decay of t

We have developed a theory that explains the spectral distribution and the different time decay behaviors of the signals observed in picosecond excitation-correlation measurements of semiconductor materials. The results display good quantitative agre
