摘要： The generation of a supercontinuum (SC) in a bulk material is an inexpensive and effective method for substantially expanding the spectrum of laser pulses. Accordingly, the broad spectrum of SC makes it ideal for seeding an Optical Parametric Chirped Pulse Amplifier (OPCPA). Stable SC in the wavelength range from ~ 500 nm to ~ 1000 nm in a YAG crystal pumped with picosecond pulses [1] simplifies TW-class laser architecture [2] due to the inherent signal and pump synchronization in OPCPA. Moreover, a stable SC in the range up to 2.5 μm would eliminate the idler generation and pave the way for the development a more reliable and compact OPCPA in the IR spectral range. We demonstrate a single-filament SC covering the wavelength range from ~ 1100 nm to more than 2400 nm, with pulse energy stability and beam pointing stability exceeding the Chirped Pulse Amplifier (CPA) - compressor [2] used as a pumping source. Such a highly stable source of broadband seed pulses together with an inexpensive CPA-compressor based on Yb:YAG rods [2] significantly simplifies the development of compact high-intensity OPCPA systems around the 2 μm spectral range.
