As I understand you need this:

<ul id="slideLinks">
<?php $slide_link = $node->field_slideshow_link['und']; ?>
<?php foreach ($slide_link as $link) : ?>
    <li><a class="slideControl" href="javascript:void(0);"><?php print $link['title']; ?></a></li>
<?php endforeach; ?>
</ul>

to print all titles.
