Abstract

A four-mirror ring cavity formed by chirped dielectric mirrors is proposed for self-mode-locked solid-state lasers. It offers, for the first time to our knowledge, the potential for approaching the gain-bandwidth limit in Ti:sapphire and related broadband lasers. Using this concept, we produced nearly bandwidth-limited 7.5-fs pulses from a feedback-initiated, self-mode-locked Ti:sapphire ring oscillator. Our experiments provide new insight into the physics and limitations of sub-10–fs oscillators.

Schematic of the MDC Ti:sapphire (Ti:S) ring laser. The pump beam is focused with a 40-mm lens onto the Ti:S crystal. M1, M3, M4, chirped mirrors; M2, chirped dichroic mirror. The radius of curvature of M1 and M2 is 50 mm.

(a) Single-scan FRAC trace of the output of the MDC Ti:sapphire laser. (b) Spectrum of the mode-locked laser measured through a pinhole positioned at (curve b) the center of the beam and (curves a and c) the half-intensity-maximum points in the horizontal plane. In the vertical plane no spatial chirp was observed.

Fig. 3
Fig. 3

Pulse duration (corrected for spatial chirp) as a function of the intracavity dispersion D at a constant intracavity pulse energy W (left-hand side) and as a function of W at constant D (right-hand side). ΔD = DD0 is the relative change of D with respect to D0 = −15 fs2, and ΔW = WW0 stands for the relative change of W with respect to W0 = 14 nJ. The solid curve is a theoretical fit of Eq. (1), from which D0 = −15 fs2 and ϕ = 0.42 × 10−6 W−1 are obtained.

Mode-locked spectra (measured at the beam center) obtained with an elliptical aperture (solid curve) and with a vertical slit (dashed curve).
