Laserglow Hercules 550 achieved ;) - But BIG PROBLEMS with Beam Expander 10x !!

Hello!
Yes, not blinking, just impulsing is the correct term!
But ALL the big powered green lasers that I have buyed, form cheaper to expensive, show the same issue: impulsing for some seconds (5-10), then start at max power and so rest forever.
I use PANASONIC PRO POWER batteries not rechargeable, the best among the alkaline model. I'm scared about rechargeable batteries: Mr. Scott told me that often the rechargeable models has an output > 1.5 volts, and this can damage the laser diode.
In Italy I have found Duracell rechargeable batteries, but the output power is about 1.2, I think too low for my Hercules.
What is the voltage output of Tenergy Premium?
My room temperature is 23 degree Celsius, so it should be a perfect temperature for use my Hercules.
I have tried to use external power supply instead batteries, but I can see the same issue.
So, the temperature is ok, the power supply also, I hope that I do not have a faulty unit like my beam expander ;(

P.S.: I do not touch the current adjust screw in any way ... it's factory preregulated for the best results!
P.P.S.: the beam in your video starts good immediatly! It seems that not impulsing in any way. Have you pre-heated You Hercules before the video, or the videocamera
is not able to capture the small impulsing?
P.P.P.S.: http://www.amazon.com/Premium-Tener.../B0040IAZ0S/ref=pd_cp_e_0/182-8678350-1593735 here You can found a really good price for Tenergy batteries!
And this: http://www.amazon.com/Ansmann-54070...4?s=electronics&ie=UTF8&qid=1324694751&sr=1-4 is the best battery charger ever! What charger have You buyed?

Any high-powered DPSS green laser will have some instability for the first few seconds of operation. Even a lab laser will have some instability when you first turn it on. It will be somewhat dependent on the ambient temperature and battery condition, but this is perfectly normal behavior.

Thanks Justin, nice to see You again And thanks for all Your efforts.

I must admit, the Laserglow service is at the top of the quality.
I have just received my new 10x optic in a nice plastic case, and this time it works very well!
I was right: in the other unit the big len was mounted in a wrong position. In this unit, the len is placed toward the end, not at the middle of the thread like the last one.
I have started a match at a distance of 30 meters. And was only my first try .. it's incredible, it's scarying
Many many thanks to Mr. Justin and Mr. Scott for the support.
A very good year to all.

Richard.
