Abstract

We describe a simple, new technique for producing of nanosecond pulses with rectangular (or triangular) temporal shape and with tunable wavelength. The technique is based on a pumping of a tunable dye laser by pulses with formed rectangular (or triangular) shape, emitted from a standard Nd:YAG (2^-nd harmonic) or Copper-vapor lasers. The pump pulses are formed in a simple electro-optical system. We have shown theoretically that the main problem to reproduce the pump pulse shape in a nanosecond dye laser -- a 'spiking' phenomenon, can be avoided using an appropriate pre-pulse pumping of the dye before the main, formed pump pulse. The experimental check confirms the theoretical predictions.
