“…For cw Ti:sapphire laser operation, we constructed a four-mirror cavity consisting of two concave dichroic mirrors, a high-reflection (HR) mirror, and an output coupler with an output coupling of 2%. The folded angle at the concave mirrors was adjusted to ~8 degrees, considering astigmatic compensation [7]. The pumping laser was collimated by an aspheric lens (focal length of 3.1 mm) and spread in direction of slow axis by a pair of cylindrical lenses with a focal length of -20 and 75 mm, respectively.…”

“…17,18 The transverse Gaussian field distribution, which is the fundamental mode in linear paraxial resonators, is widely used as an approximate description for the transverse field distribution in nonlinear resonators. 3,4,19 In addition, the Gaussian trial function can conveniently be characterized in terms of the complex q parameters, which allow for a compact description of the optical propagation based on the ABCD matrix formalism. 15,16 In the following, the Gaussian equations of motion, obtained by the Kantorovitch method, are given for the spatial beam propagation and the temporal pulse evolution in a Kerr medium with a parabolic transverse and spectral gain profile, as well as for the full spatiotemporal dynamics.…”

“…The nonlinearity coefficients are now given by c a = 1/4 and c φ = 3/4, which are the same as derived using the method of minimum weighted square mean error, 20 but different from the results obtained by a Taylor expansion. 19 The propagation equations for the purely temporal pulse dynamics are obtained by setting B = g x = g y = 0 in Eqs. ( 1) and ( 2).…”

Using the Kantorovitch method in combination with a Gaussian ansatz, we derive the equations of motion for spatial, temporal and spatiotemporal optical propagation in a dispersive Kerr medium with a general transverse and spectral gain profile. By rewriting the variational equations as differential equations for the temporal and spatial Gaussian q parameters, optical ABCD matrices for the Kerr effect, a general transverse gain profile and nonparabolic spectral gain filtering are obtained. Further effects can easily be taken into account by adding the corresponding ABCD matrices. Applications include the temporal pulse dynamics in gain fibers and the beam propagation or spatiotemporal pulse evolution in bulk gain media. As an example, the steady-state spatiotemporal Gaussian pulse dynamics in a Kerr-lens mode-locked laser resonator is studied

“…The folded angle at the concave mirrors was adjusted to ³8°, considering astigmatic compensation. 16) For CW operation, the SESAM was replaced by a high-reflectivity (HR) mirror; however, the two chirped mirrors were retained. In our pumping setup, ³66% of the pump power was absorbed in the crystal in a single pass, and CW operation at a wavelength of 802 nm was confirmed.…”
