“…The rise of Yb laser technology enabled generation of high-energy femtosecond and picosecond pulses at very high repetition rates ranging from 100s of kHz to a few MHz with excellent beam quality, beam pointing and energy stability, thus making feasible construction of high average power OPCPA systems. To this end, Yb:KGW 45,46 , Yb:YAG 47 , Yb-fiber 48 master oscillatorpower amplifier systems and high power Yb:YAG amplifiers exploiting bulk 49,50 , thin-disc 51 and Innoslab configurations 52,53 were developed as integrable parts of OP-CPA setups. Finally, novel Ho:YAG 54 and Ho:YLF…”

The generation of power-and wavelength-scalable few optical cycle pulses remains one of the major challenges in modern laser physics. Over the past decade, the development of table-top optical parametric chirped pulse amplificationbased systems was progressing at amazing speed, demonstrating excellent performance characteristics in terms of pulse duration, energy, peak power and repetition rate, which place them at the front line of modern ultrafast laser technology. At present, table-top optical parametric chirped pulse amplifiers comprise a unique class of ultrafast light sources, which currently amplify octave-spanning spectra and produce carrier-envelope phase-stable, few optical cycle pulses with multi-gigawatt to multi-terawatt peak powers and multi-watt average powers, with carrier wavelengths spanning a considerable range of the optical spectrum. This article gives an overview on the state of the art of table-top optical parametric chirped pulse amplifiers, addressing their relevant scientific and technological aspects, and provides a short outlook of practical applications in the growing field of ultrafast science.

“…We investigate only the effect of this technology on the laser itself, and do not present any results relating to an increased stability in the entire laser system of which this pump is one part. With the advent of new scientific facilities that use OPCPA incorporated in their systems coming online [6][7][8][9], stabilization of the pump energy is crucial. Moreover, we can envision that this same system could be applied to a wide range of lasers as long as they are not single-shot lasers.…”

We present a method for regulating the laser energy output with a software-controlled waveplate–polariser configuration. By implementing this technology, we have effectively eliminated energy output fluctuations over time, allowing for the laser to reach its nominal energy up to 2 h earlier. Our testing demonstrates a stability of 2.8% (RMS), verifying the system’s reliability. We provide an overview of the software and its basic operation, along with practical evidence of the system’s efficacy in maintaining a stable laser energy output.

“…Compared to nanosecond pulses, picosecond lasers have a higher peak power that can control the processing depth and precision more effectively and greatly improve the processing quality [11][12][13]. Meanwhile, compared to femtosecond pulses, picosecond lasers achieve high-power output with higher stability easier [14][15][16][17]. In addition to achieving a highpower output, short-pulse lasers at specific wavelengths are also necessary for various applications.…”

Picosecond lasers with high average power and high beam quality have been widely used for precision processing and space exploration. In this study, we report a high-power picosecond green laser using a multistage Yb-doped rod-shaped photonic crystal fiber as an amplifier combined with a beam combination. The single amplification module achieves a 1,030 nm laser output of 146.8 W, and the maximum second harmonic generation (SHG) power is 92 W with a frequency conversion efficiency of 63.5%. The combined beam of the two SHGs resulted in a final output of 178 W with a repetition frequency of 24.07 MHz, pulse width of 50.1 ps, and beam quality factor of M2 = 1.16. Furthermore, an adaptive filter control method of a two-axis fast-steering mirror was applied to suppress the beam jitter to up to 45 Hz.
