Abstract / Description of output

In this Letter, we use a reconfigurable hologram to dynamically control the position of incidence of the pump beam onto a liquid crystal dye-based laser. The results show that there is an increase in both the stability of the laser output with time and the average power when compared with the output of the same laser when it is optically excited using a static pump beam. This technique also provides additional functionality such as wavelength-tuning and spatial shaping of the pump beam, both of which are demonstrated here.
