• "Note that this is not a pure absorbing sail, since the excited ions will re-emit the incident light in about 100 ns depends on linewidth."
• "The narrow linewidth and frequency stability of the NeoPhotonics NLW-TL are enabled by a phase-shifted DFB laser chip and proprietary packaging technology, and the laser assembly includes an integrated wavelength locker as well as electrical and firmware interfaces."
• "NeoPhotonics NLW-TLs are compact, widely-tunable and narrow linewidth assemblies with up to 35mW launch power in the C band and 20mW in the L band."
