depthimage_to_laserscan takes a depth image (sensor_msgs/Image), converts it to a Laserscan (sensor_msgs/LaserScan) and publishes it. No "output window" is created.

By default the LaserScan is published on the /scan topic. You can check it exists with rostopic list | grep "/scan"

To visualize it, the most common would be to add a LaserScan topic in RViz and select the /scan topic.

If this doesn't answer your question, can you please edit it to provide more information:

• What you are trying to accomplish
• What "response or output window" you expected?
• "i can easily get rgb, ir and depth images using rosrun commands" -> What commands are you referring to ?
• Any useful additional information following the Support Guidelines
