Abstract. We report the theory and experiments of a two-wavelength bi-tuning femtosecond Ti:sapphire laser. The cross-mode-locked gain competition is described with numerical solution and operation of the laser is accomplished in which two trains of femtosecond pulses cross in the Ti:sapphire rod. For this reason, a cross-bearings technique is used. The laser resonator is a six-mirror bi-cavity, and two beams of pump lights cross in Ti:sapphire crystal. Two trains of sub-30 fs cross-mode-locked pulses have been generated with independent tunable wavelength when the pump power of the argon laser is approximately 5 W. As the design of the bi-cavity is fine, not only strong gain competition is overcome, but also stable output characteristics are performed.
