Coherent combining of quantum cascade lasers
Powerful sources in the mid-infrared with a good beam quality are highly needed for applications such as optical countermeasures. The quantum cascade laser (QCL) is a... -
Coherent combining of femtosecond fiber amplifiers
Applications addressed by femtosecond (fs) laser sources are requiring increasing pulse energies and increasing average powers. Ytterbium-doped fiber amplifiers are...
