Book Description
Carbon Monoxide vapor is used to generate coherent, tunable vacuum ultraviolet radiation by third-harmonic generation using a single tunable dye laser. The presence of a nearby electronic level resonantly enhances the nonlinear susceptibility of this molecule allowing efficient generation of the vuv light at modest pump laser intensities, thereby reducing the importance of a six-photon multiple-photon ionization process which is also resonantly enhanced by the same electronic level but to higher order. By choosing the pump radiation wavelength to be of shorter wavelength than individual vibronic levels used to extend tunability stepwise from 154.4 to 124.6 nm, and the intensity to be low enough, multiple-photon ionization can be eliminated. Excitation spectra of the third-harmonic emission output exhibit shifts to shorter wavelength and broadening with increasing CO pressure due to phase matching effects. Increasing the carbon monoxide pressure, therefore, allows the substantial filling in of gaps arising from the stepwise tuning thereby providing almost continuous tunability over the quoted range of wavelength emitted.

Book Description
When after three decades of research Singapore could produce its own water, the little city-state was said to have lost its vulnerability. No longer would every policy have to bend at the knees for water survival. It was finally time to celebrate liberty!When did the same moment come in Bala's life? Was it when in mid-Atlantic he heard of his promotion as Controller of Posts? Or was it when he was appointed by the President as member of the Parliamentary Elections Minority Committee? Or was it at a moment of tragic loss when he realised he had nothing more to lose?Singapore, My Country tells M Bala Subramanion's story, a second generation Indian who lost his father to the Death Railway, witnessed Subhas Chandra Bose at the Padang and later emerged as not only a senior civil servant but the man behind multiple social interventions, living in a fast evolving Singapore.The histories of the man and his nation remain seamlessly intertwined, each peppered with equal doses of endeavour, ingenuity and a sheer will to survive!
