If you have ever worked with lasers, you know how fun and interesting it can be, you also know how expensive it can be. The high voltage power supplies for the laser tubes are often more expensive then the tubes themselves. This supply can be built with commmon parts, most of which you probably already have in your junk box. The secret is the transformer used. It is a common 9V 1A unit, connected backwards for step up. |
Please note that some people may have trouble with this supply. This is due to the slight difference in transformers. For more information on LASER power supplies, take a look at Sam Goldwasser's Laser Supply Info Page.

| what kind of lasers are used for the power supply. | ||
| sir, this is very good project thank you. | ||
| thanks very much | ||
| Looks like people are running off-tangent with a lot of twisted theory! The Circuit CAN work , pretty well!! James Martin: Dont go by assumptions. Current is Drawn by the load. dont think you know the Laser, but it is 2mW!! Even if the O/p current is 1mA, you can see that the I/P current is fairly small. Some thing like 1W , without the relevant electronic calc. anonymous: Learn physics first, along with good English. The 1N4007 is rated for 1KV max. 3 in series will stand the o/p voltage of 3KV. since the output is 1500V, the diodes have a good chance of surviving the RMS values. ( or even the peak value). Guys : Please stop commenting about anything, without some serious homework! | ||
| bullshit. Test your schematics before publishing. (Editor's notes: Tested and verified with a 2mW HeNe tube.) |

| I don't understand how this circuit can load R(load) with 1500V ?? We have only 9V in the output !!! | ||
| It's great. I like it. I want to try it at my university lab. How are the output wave forms? I mean does the circuit make a fine dc output? How much is the ripple factor. And can you send me the answers for James Martin's and Sandeep's questions that are posted on you website? Thank you!Keep it up!boy | ||
| Sir, this a very nice topic but i can't understand whole thing can you send me the whole project report on my yahoo id I always thankful to your great honour | ||
| provide a perfect circuit which will help to find a perfct laser power supply | ||
| it is great but can you elaborate what kind of tube is it? | ||
