Mode-locking of a CW laser 1 Introduction
... Short pulses are useful in a number of applications in optics, e.g., time resolved spectroscopy, sampling of fast electronics, and communications. This has led to a number of mode-locking techniques to obtain such pulses, for example acousto-optic, injection, synchronous-pump, collidingpulse mode-lo ...

... The Letter by Deng et al. [1] presents an analytic theoretical description of matter-wave superradiance [2] which claims to go beyond previous theoretical frameworks. I show here that the theory presented in this Letter is not a description of superradiance per se, but rather an elegant perturbative ...
