Compact, ultrastable, high repetition-rate 2 μm and 3 μm fiber laser for seeding mid-IR OPCPA.

We report a compact and reliable ultrafast fiber laser system optimized for seeding a high energy, 2 μm pumped, 3 μm wavelength optical parametric chirped pulse amplification to drive soft X-ray high harmonics. The system delivers 100 MHz narrowband 2 μm pulses with >1 nJ energy, synchronized with ultra-broadband optical pulses with a ∼1 μm FWHM spectrum centered at 3 μm with 39 pJ pulse energy. The 2 μm and 3 μm pulses are derived from a single 1.

Effect of human chorionic gonadotropin on uterine blood flow in intact and ovariectomized gilts.

This experiment was designed to test the hypothesis that human chorionic gonadotropin (hCG) can directly influence uterine blood flow in pigs. In the study, 18 crossbred gilts (95-100 kg) which had exhibited at least one estrous cycle were used: 8 cyclic gilts in the luteal phase of the estrous cycle and 10 gilts ovariectomized (OVX) three weeks before the experiment began. The OVX animals received i.
