Simple 1N4007 Silicon Diode Laser Power Supply Circuit

This is a circuit power supply. This circuit is design for laser. This is the figure of the circuit;

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.
