How to make laser 'bend' 90°

I am working on a game in which the player has to adjust the position of blocks to reflect a laser and help it reach its endpoint. For this I need to be able to figure out how to make the laser 'bend' 90° when it hits a block. Is there any way of either creating such a laser or doing it with, for example, this asset:

Sorry if this is something very obvious and easy - I've only just started using Unity
