“…In this letter, a homogeneously broadening amplification process is considered and we assumed that the population inversion densities are uniform, thus a simple one-dimension model [22] is employed here. Since the purpose is to evaluate the hybrid laser performance on alleviating the gain narrowing, spectral phase distortion is not taken into account.…”

“…The same set of equations was used for the simulation of the pumping process by accounting for the inversion decay losses during the pumping times. The presented simulation method can be computed in less time as compared to simulation methods that involve numerically more complex rate equations [10]. This is of particular importance for example to statistically analyze the noise and bifurcation behavior of RAs, or to finely sample certain parameters over a wide parameter space.…”

Numerical study of spectral shaping in high energy Ho:YLF amplifiers

We present a new chromatic numerical approach to simulate the amplification of laser pulses in multipass laser amplifiers. This enables studies on spectral effects such as gain narrowing and spectral shaping with optical elements expressed by a transmission transfer function. We observe good agreement between our simulations and measurements with a Ho:YLF regenerative amplifier (RA). To demonstrate the capabilities of our simulation model, we numerically integrate an intra-cavity etalon in this laser and find optimum etalon parameters that enhance the peak power of the output pulses up to 65%.

“…Beam propagation can also be severely influenced by thermal lensing. 16,17 In the multipass amplifier of a high-peak-power laser system, the output beam spot size will be notably reduced due to thermal lensing. The higher the pump energy and the more times the beam passes through the gain medium, the smaller the output beam spot size will be.…”

Development of a compact efficient 10 Hz 20 TW Ti:sapphire laser system with a 1 kHz regenerative amplifier

et al. 2007

We have constructed a compact efficient Ti:sapphire laser system that generates 30 fs, 630 mJ pulses at a repetition rate of 10 Hz. A new geometry for a single-stage multipass power amplifier is proposed that greatly weakens and even makes use of thermal lensing. Such geometry can realize high output in a single-stage power amplifier; otherwise at least two-stage power amplifiers are required. The new configuration simplifies the laser system and reduces the cost. The key point in this design is that the beam spot size evolution is considered in combination with the pulse amplification.
