The introduction of a glass prism in a ring dye laser is shown to provide simultaneous wavelength selection and pulse compression.

A tunable ArF* (193-nm) excimer source is described that produces over 125 mJ/pulse (peak) at 10 pulses/sec. This device has a spectral width of less than 2 cm(-1) and a demonstrated tunability of nearly 320 cm(-1) from 192.8 to 193.9 nm. Tunability, bandwidth, and mode control are achieved by injecting the fourth anti-Stokes line (in H(2)) of a frequency-doubled dye laser into an ArF* excimer-...

For the first time, we reported the strong electrogenerated chemiluminescence of organic dye, bis[4-(dimethylamino)phenyl]squaraine (BDPSQ), a high quantum yield and light-stable species, which might find applications in ECL analysis and imaging.

The current commercial application of ink-jet reactive inks to cotton fabrics has been through pre-treating with pad liquor prior to printing. In This study made an effort to provide a single phase ink-jet printing process for printing cotton fabric using the novel cationic reactive dye in ink’s formulation. Cotton fabric was printed upon with the novel cationic reactive dye and commercial anio...

Atmospheric NO was detected in a long-path absorption experiment using a frequency-doubled dye laser, twice Raman shifted in H(2) to 227 nm. Apart from measurements employing a distant retroreflector, the potential of range-resolved lidar measurements was investigated.

Illumination systems with tunable spectrums have been receiving an increasing amount of attention due to their wide application and unique capability. This paper proposes a programmable light source in the visible range based on the combination of a prism and an echelle grating. A supercontinuum laser is utilized as the primary source, whose echellogram is projected to a digital mirror device f...

The passive mode locking of a cw Coumarin 6 dye laser in a colliding-pulse ring configuration is reported. Pulses of less than 500-fsec duration have been obtained from 518 to 554 nm, with the shortest pulses obtained being of 96-fsec duration.
