Here if you are using the this._location.back() to go back you can pass only the index to this function. How much index you want to go back from browser history.

For Example to go 2 index back

this._location.back(2);

Example to go back with queryParams 

this.router.navigate(['/test2', { id: 12321313}]);

Check for angular 2 declaration function location.back() inside @angular\common.js

class Location {
     /* Navigates back in the platform's history.*/
     /* @return {?} */

    back() { this._platformStrategy.back(); }
 }

InShort the thing what you are trying this._location.back(2) work same as window.history.back(); and accept only the index value you want to go back from browser history
