We report on the optimization of a long-cavity, chirped-pulse Ti:Sapphire oscillator to achieve maximum pulse energy for a given pump source. Effects of the intracavity dispersion on the output spectrum of our laser are studied in detail experimentally. We also present considerations on the cavity length optimization that can be achieved with a given set of resonator mirrors to achieve more energetic pulses. The output of the laser delivered chirped 200 nJ pulses that are compressible to ∼ 40 fs. The pulses can be ideally used for a white-light and/or few-cycle source with a subsequent extracavity spectral broadening stage. A graph is presented. The spectrum of the chirped pulse oscillator (solid line with shaded area) together with the reflectivity of the SBR used (dash-dotted line) and the intracavity GDD of the laser (dashed line) as a function of wavelength.
