Stilbene Dye Lasers - Properties and Applications

Stilbene is a relatively colorless, unreactive compound that is highly insoluble in water. Stilbene derivatives are thermally and chemically stable, and have absorption and fluorescence properties that can be monitored through relevant optical techniques. Substituted stilbene molecules are widely used as blue dye lasers, having a wavelength range of 400-450nm.

The key properties of a stilbene laser include the following:

  • High stability
  • Good efficiency
  • Broad tuning ranges

The laser uses stilbene as the active saturable gain medium. Stilbene dye lasers are usually pumped at shorter emission wavelengths. The pumping source for stilbene dye lasers can be ultraviolet light, solid-state laser, excimer laser, or flash lamps. However, pumping with flash lamps can lead to the generation of longer pulses, and low power conversion efficiency.
