Nitrogen-laser-pumped single-mode dye laser
- 79 Downloads
Single-mode operation of a N2-laser-pumped'dye laser has been obtained in a short laser cavity consisting of a diffraction grating used near grazing incidence and an uncoated resonant reflector. The dye laser pulse has a spectral linewidth of 420±30 MHz and a pulse width of 1.1±0.1 ns, giving a time-bandwidth of 0.46±0.07 close to the Fourier transform limit for Gaussian pulse.
