We review the principle, design and output characteristics of the MPQ/LMU LWS-1 mid-infrared few-cycle OPCPA system. With the output of CEPstable 2.1-μm-700-μJ 15-fs (2-optical-cycle) pulses at 1 kHz, this laser is unique in the world, providing the shortest sub-mJ pulses in the mid-infrared. A system upgrade with a Yb:YAG thin-disk pump laser has recently produced 1.2-mJ 1.5-cycle pulses at 3 kHz, approaching the TW-level monocycle regime.
