We report on our progress in the development of a 1 J-class Yb:YAG laser system with a repetition rate of 100 Hz for OPCPA pumping. We have demonstrated amplification of 10 ns pulses to 1 J at 100 Hz by using a multi-TRAM.

2015 11th Conference on Lasers and Electro-Optics Pacific Rim (CLEO-PR).
We report on our progress in the development of a high-pulse-energy Yb:YAG laser system for OPCPA pumping. We have demonstrated generation of 160-ps chirped-pulses with a spectral bandwidth of 0.12 nm and a pulse energy of a few mJ by using a Yb:YAG

Antioxidant effect of the Ocimum flavonoids, orientin and vicenin (25-500 M), was evaluatedby the kat-sod assay in Escherichia coli mutants (DSH56, superoxide dismutase-deficient andDSH19, catalase-deficient) treated with 50 mM menadione or H2O2 (1mM

A simple and compact spectral-broadening system is presented that is based on a single-stage statically pressurized Ar filled hollow core fiber. By optimizing the inner diameter of the hollow core fiber, a bandwidth of 300 nm is obtained. This is the

Stimulated Raman scattering driven by differential coupling of two phonon modes has been demonstrated. These phonon modes are coherently and strongly coupled by external fields via two-phonon excitation at the first Brillouin zone boundary. Up to 11t

Since it has been considered that suppression of spontaneous mutation in cells is related to suppression of spontaneous carcinogenesis, it is significant to detect substances which suppress spontaneous mutation in bacterial cells such as Escherichia
