It looks like a combination of TEM00 and TEM01 mode. The presence of even higher order modes than TEM01 cannot also be denied.<br /> [[Category:1064crystalaser]]</div> Thu, 15 Nov 2012 01:50:38 GMT Pranav Rathi http://openwetware.org/wiki/User_talk:Pranav_Rathi/Notebook/OT/2010/03/11/Brief_mode_profiling_of_coherent_compass_laser
