  We present a Ho:YLF Chirped-Pulse Amplification (CPA) laser for pumping a
longwave infrared Optical Parametric Chirped Pulse Amplifier (OPCPA) at a 1 kHz
repetition rate. By utilizing a Ti:Sapphire laser as a frontend, 5-{\mu}J seed
pulses at 2051 nm laser pulse are generated in a Dual-Chirp Optical Parametric
Amplifier (DC-OPA), which are amplified to 28 mJ pulses with a pulse duration
of 6.8 ps. The scheme offers a potential driver for two-color (800 nm and 8
{\mu}m) high harmonic generation with an increased keV X-ray photon flux.
