No, it only works when it is needed. A laser has limited working life, and to extend the working life, they will not work when there is no command. It will turn of automatically when there is no disc.
BTW, you may also meet problem of no disc error even there is a disc in the drawer. You can check this guide for help.

There are a lot of DVD players having "no disc" issue especially after years of using. Then how to fix the "No disc" and let the player play your disc successfully? If you are sure that there is something wrong with your player, you can press the "Eject" or "Open" button on the DVD player to disc tray to determine if it opens easily and does not appear jammed or hindered. If the disc tray appears to open slower than usual or fails to open, the disc may not sit flush in the tray or otherwise be seated properly. Most of the DVD "No disc" problems are caused by the glitch of DVD laser lens. You can start out by trying to blow away the dust, if that doesn't work, you can try using a DVD cleaning disc. If you think it's too expensive, you can also open the player and clean it manually.
