Automatic repeated sound

I'm making a Geometry Wars/Asteroids kind of top down shooter. I'm using raycasts as my bullets and I have a script that shoots the raycasts at an interval, simulating an automatic laser (see below.) Is there some way I could make a "laser blast" sound play at the same time that the raycast is shooting? I want to add sound to the laser, but don't know how to do it. Can someone please help?

P.S Here's the code I use for my laser

 var fireRate : float = 0.5;
 var Range : float = 1000;
 var Force : float = 75;
 private var nextFire : float = 0.0;
 
 function Update(){
     if(Input.GetButton("Fire1")&& Time.time > nextFire){
         nextFire=Time.time + fireRate;
         RayShoot();
     }
 }
 
 function RayShoot () {
     var Hit : RaycastHit;
     var DirectionRay =transform.TransformDirection(Vector3.forward);
     Debug.DrawRay(transform.position , DirectionRay * Range , Color.blue);
     if(Physics.Raycast(transform.position , DirectionRay , Hit, Range)){
         if(Hit.rigidbody){
             Hit.rigidbody.AddForceAtPosition(DirectionRay * Force , Hit.point);
         }
     }
 }
