That is normal. The crystal set works optimal in specific range of temperature. Too cold or too hot and the power is under par.
All DPSS laser behave like this.

JUST DONT LOOK AT THE LASER BEAM!!!!It outputs IR like normaly, but the crystal like messes up and wil do about 1/8 of the work it should.

so if it is not overspec so it is not a big deal to look at the beam. But its not good because your eye gets biger to catch more light to see better, it lets more light to hit the eye.If you would look at the sun with your eye big, your eyes would get BURNED

Actually the pump diode wavelength is temperature dependent, this is the major cause of the power fluctuations. KTP only gets slightly more efficient at higher temperatures and Nd:YVO4 just needs to be kept from overheating.
