    Dual-wavelength operation of a flashlamp-pumped Ti:sapphire laser employing a modified grazing-incidence grating resonator with two tuning mirrors is described. Spatially resolved laser spectra in the output beam at the near field indicate that a large part of each wavelength laser beam oscillates in the separated gain volume. Linewidth of ˜16 pm is achieved for both laser wavelengths. Simultaneous second-harmonic generation of the dual-wavelength laser is also demonstrated in the spectral range of 390–420 nm with a β-BaB2O4 nonlinear crystal. The phase-matching angle of each wavelength is automatically satisfied in a fixed optical arrangement by using four dispersive prisms and a lens.
