“…To study the effect of B-integral in low-energy-seeded regenerative amplifiers, a simple 1-D model propagating the gain medium inversion and wavelength-dependent pulse energy buildup for the full pulse train is developed, where the nonlinearity on the amplified pulse caused by the PC and air is calculated in each round trip. The populations in the ground and excited state manifolds are calculated based on the rate equations for continuouslypumped Yb:YAG [16] and the gain in each pass is obtained via the temperature-dependent emission cross-section according to [17].…”

“…A Yb:YAG thin-disk regenerative amplifier as described in [6], is used for experimental verification of these effects in this study. In this system, the 1 pJ pulses centered at 1030 nm, driven from a Ti:sapphire oscillator were amplified to 80 pJ exploiting a diode-pumped, fiber pre-amplifier [9,17,18]. A second fiber pre-amplifier was placed after the pulse picker for further amplification of seed pulses up to 40 nJ.…”

The dynamics of chirped pulse amplification in thin-disk regenerative amplifiers relevant to the pumping of optical parametric chirp pulse amplification systems are described. It is shown that the suitability for reproducible pumping of subsequent nonlinear processes requires a balance between the demands of avoiding chaotic pulse train dynamics and providing a reproducible spectral phase. We describe measures that may be taken to ensure that a laser system operates in the desired stable regime.

Compact high power broadband superfluorescent fiber source has been demonstrated using an ultrashort Er3+−Yb3+-codoped phosphate glass fiber. The fiber is 10.4-cm-long and at 1.68 W pump power, an output power of 16.85 mW, a mean wavelength of 1540.9 nm, a bandwidth of 18.4 nm, and a slope efficiency of 18.6% have been obtained. The dependence of output power, mean wavelength, and bandwidth stability on pump power and fiber length are also studied, and there is an excellent agreement between the theoretical results and experimental data.

This article presents the fundamental principles of operational performance of a continuous wave (cw) thin-disk laser with multiple disks in one resonator. Based on the model of an end-pumped Yb:YAG thin-disk laser with nonuniform temperature distribution, the effect of the multiple disks in one resonator is considered. The analytic expressions are derived to analyze the laser output intensity, laser intensity in the resonator, threshold intensity, and the optical efficiency of a thin-disk laser with multiple disks arranged in series. The dependence of output coupler reflectivity and the number of thin disks on various parameters are investigated, which are useful to determine the optimal output coupler reflectivity of the thin-disk lasers and control the laser intensity in the resonator.
