Phys. Rev. Lett. 73, 3544–3547 (1994)Hose-Modulation Instability of Laser Pulses in PlasmasReceived 6 June 1994; published in the issue dated 26 December 1994 A laser pulse propagating in a uniform plasma or a preformed plasma density channel is found to undergo a combination of hose and modulation instabilities, provided the pulse centroid has an initial tilt. Coupled equations for the laser centroid and envelope are derived and solved for a finite-length laser pulse. Significant coupling between the centroid and the envelope, harmonic generation in the envelope, and strong modification of the wake field can occur. Methods to reduce the growth rate of the laser hose instability are demonstrated. © 1994 The American Physical Society URL:
