For the most part, this is a configuration setting in most modern browsers that the user controls. However, if you specify window dimensions and/or features on the window.open call, some browsers may open a new window when they otherwise would have opened a new tab. For example:

window.open("mypage", "_blank", "width=400,height=200,menubar=no,toolbar=no");

At the end of the day, though, it's stil down to the browser implementation, and as ever, you'll need to test to ensure you're getting the results you hope for across the majority of browsers your app/site supports/typically sees.

This article might be of help: http://www.blazonry.com/javascript/windows.php. You need to specify size attributes.

window.open(myUrl, "_blank", "width=640,height=480,menubar=no,toolbar=no");
