Transient excited singlet state absorption in Rhodamine 6G
Putcha Venkateswarlu M C George Yerneni V Rao H Jagannath G Chakrapani A Miahnahri
Transient excited singlet state absorption (ESSA) has been studied in Rhodamine 6G in ethanol using a nitrogen laser and nitrogen laser-pumped dye laser. Broad absorption with several submaxima and possible shoulders, which represent the vibrational structure, has been observed in Rhodamine 6G in the region, 4175–4640 Å. The position of the lowest vibrational level of the first excited singlet state

Beam couplings and phase conjugate effects in reflection and transmission in BaTiO3
Putcha Venkateswarlu M Moghbel P Chandra Sekhar M C George
The details of experiments showing the effects of self-pumped phase conjugation on reflection and on transmission in barium titanate crystal are given. The specular reflection and the second-surface reflection of an extraordinary polarized beam, incident on the face of the crystal parallel to its
