I'm sorry but I don't have a background in Chemical, Biological or Warfare lasers. My background covers Co2, Ho, Ho:YAG, Erbium, YAG and Q.S.YAG and visible light.

The Laser Doctor is taking your laser questions.........

The Doctor is leaving for the day. I will see you same laser time, same laser channel. !

Physics hasn't escaped the Doctor. My point to the question is very difficult to answer. Co2 laser beams do not contain heat. The absorption of the Co2 laser light into a particular object such as...

I think he means High voltage supply or RF supply

The Laser Doctor is leaving for the weekend. See you same laser time, same laser place Monday.

Yes, tubes can degrade sitting on the shelf. They should last a minimum of 3 to 5 years sitting around. I also like the picture that was sent on the electrical leads. It should be checked.

Sure. Your problem is the gas mix in the laser tube or a small leak that has developed. The mixture on these tubes is disassociating causing a reduction in current drive. Always suspect the power...

I'm here. The Laser Doctor was off yesterday playing golf.

..and give Rodney Gold a cudos for his comment on spot size cutting.

Boy, I didn't realize I opened pandoras box. The comments above are all correct. I was simply trying to state, shorter focal lengths produce smaller spot sizes. longer focal lengths produce larger...

Sorry, I don't have an answer for you.

Wow, what a great question. I honesty don't have an answer for you. Maybe someone in the community can answer it. Now, I have seen many laser cutters of sheet metal. However, they usually start...

It sounds like the current regulator has stopped working. You basically have the one setting without adjustment with the power control. The test button is just a signal to fire the supply. I assume...

Yes laser tubes are under vacuum, just like a light bulb.

The gas mixtures are kept highly secretive. There are numerous combinations depending upon the laser type DC or RF. The base mixture is Co2/N2/He.

I never have seen this. But the answer is simple. The mirrored surface is silver plated, not a reflective as true laser coating. This also sometimes appears as gold plate. Also works as a reflector....

It's not gold. This is an Anti-Reflection coating that the manufacture puts on both sides of the lens. The lens without the AR coating will reflect 4% of the laser power, 2% each side of the lens or...

The Doctor pressed the wrong button this morning. Sorry.

The Laser Doctor has checked in. Looking to answer your laser questions.

The Laser Doctor is leaving for the day. A very slow day for the Laser Doctor. No office calls today. See you tomorrow, same laser time, same laser channel.

The Laser Doctor is in.......

Sorry the Laser Doctor does not have a answer to your question. If I were to guess..mmm. the temperature would approach that of the sun.

Good Morning the Laser Doctor is in. RF stands for Radio Frequency. Companies like Synrad Lasers and Coherent Lasers are RF excited. Try looking at companies like Laser Resale or Photovac Laser...

Try Ebay

Good morning the Laser Doctor is in. Yes, I am sure of the number. This figure is well document for some manufactures RF lasers. I can also assure you, that this number is not realized what so ever...

The Laser Doctor will see you Monday. Same laser time, same laser channel!

I always say more power, more speed. The higher the power the greater cutting depth and less time to perform the task. Cutting depth is dependent upon a few things. Consider beam diameter and the...

Unfortunately I need to keep my background "Super Secret" . As time progress, you will see I 'm well qualified to answer your laser questions. I certainly have a rich background in all laser...

Well, if you actually lase for 8 hours a day, your hours are basically correct. Try measuring actiual lasing time. Time on only. You may only turn the laser on 4 hours in your 8 hour day. 210 days a...
