Stable 1100–2400 nm Supercontinuum in YAG with Picosecond Pumping for Simplified OPCPA

High-efficiency bismuth borate-based optical parametric chirped pulse amplifier with approximately 2.1 mJ, 38 fs output pulses at approximately 2150 nm

“…However, the direct use of the SC seed in the SWIR range allows the OPCPA configuration to be simplified by eliminating the need for active synchronization between the seed and pump lasers. Although generation of the SC in the SWIR range is difficult with femtosecond pump sources [ 28 ] , it is easier to implement using single-picosecond pulses at a wavelength of 1 μm [ 29 ] . Moreover, an OPCPA pumped and seeded with ps pulses makes it possible to reduce the TOD accumulated in the system.…”

Synthesis of Adjacent Stokes Spectra in a Two-Stage Transient Stimulated Raman Chirped-Pulse Amplifier

“…The Yb:YAG chirped-pulse amplifier [15] used in the experiments delivered ~1.2 ps (FWHM) transform-limited pulses with an energy of 20 mJ at a repetition rate of 100 Hz (Figure 1). A small portion (~12 μJ) of the laser pulse energy was directed to an undoped YAG rod 15 mm long to obtain stable SC pulses in the wavelength range from 1050 to 2400 nm [16]. These SC pulses were used to seed the first TSRCPA stage.…”
