To this end, we consider a combination of two magnetooptical (MO) phenomena, the Cotton-Mouton and Faraday effects, in order to introduce a suitable and tunable interplay between the induced linear and circular birefringences. Our numerical analysis confirms that a properly applied external magnetic field may alter the dynamics of the beam propagation in magnetic self-focusing bulk Kerr media. For a chosen value of the optical power, the acceleration, the delay or even the arrest of the collapse can be achieved. We demonstrate experimentally the magnetically-induced acceleration of the collapse in a ferrimagnetic yttrium iron garnet crystal (YIG). <br /> <br />Full Text: <a class="file" href="/PLP/index.php/letters/article/view/1-56/58" target="_parent">PDF</a> <br /> <strong><br />References:</strong> <ol> <li>R.W.
