What Kind of Parts Do You Need for Lasers, and How to Find Them


In order to build a laser, you need a few specific parts. This article will discuss what those parts are and where you can find them. You will also get some tips on how to choose the right components for your needs. So, whether you're just starting out in the laser world or you're looking for an upgrade, read on for more information.


This is the most essential component of any device of this kind. Finding high-quality Laser Diodes will ensure the proper functioning of your device and will also prolong its lifespan. You can find these diodes on various online platforms that sell electronic components.

When looking for diodes, consider the power rating of the diode. This is usually expressed in watts (W). The higher the power rating, the more powerful the diode. However, you should also consider the price when making your decision. Higher-powered diodes are usually more expensive than lower-powered ones.

Another factor to consider is the wavelength of the diode. This is measured in nanometers (nm). Diodes with shorter wavelengths are more powerful and can be used for industrial applications. Diodes with longer wavelengths are less powerful and are better suited for home use.

Driver circuit 

A high-quality driver circuit is a critical part of any laser driver. It provides the necessary current and voltage to the laser diode to operate correctly. A good driver will also have a way to monitor and control the temperature of the laser diode, as well as protect it from electrical damage.

There are many different types of driver circuits available on the market, so it is important to choose one that is compatible with your specific laser diode. You can typically find this information in the datasheet for your diode. If you are unsure, please consult with an expert before making a purchase.

Think about what features are important to you and then find a driver that meets those needs. Some factors you may want to consider include maximum current output, minimum voltage drop, efficiency, as well as cost.

Once you have chosen a driver, be sure to follow the manufacturer's instructions for installation and use. Improper installation or use of a driver can damage your laser diode and void any warranties that may be included. 

A solder  

Solders are important for multiple reasons when it comes to making lasers. These are the following:

  • They can hold together different objects
  • They can be used to attach an object to a board 
  • They have a low melting point
  • They are electrically conductive. 

All of these factors are important when choosing a solder for your project. You want to make sure that the solder you choose can do all of the tasks that you need it to do. 

There are a few things that you should keep in mind when looking for a good solder: 

  • Find a solder with a low melting point so it can melt quickly and easily.
  • Find a solder that is electrically conductive so the electrical current is able to flow through the solder easily. 
  • Find a solder that is strong so you hold different objects together. 
  • Find a solder that is easy to use so you're able to attach an object to a board easily. 

If you keep all of these factors in mind, then you should be able to find a good solder for your project.

Soldering iron 

You will also want to have a soldering iron on hand to help with the construction of your laser. Soldering irons come in a variety of shapes, sizes, and types, so it is important to choose the one that best suits your needs.

There are three main types. Manual soldering irons require you to manually adjust the temperature. Automatics, on the other hand, have a built-in sensor that automatically adjusts the temperature based on the task at hand. Finally, temperature-controlled soldering irons allow you to set and maintain a specific temperature. This is important for delicate soldering jobs.

Assess these features and choose wisely as your success will depend on them. 

DVD disk burner

Believe it or not, you can use a DVD disk burner to make a laser. This device is important because it helps to create a beam that is intense enough to cut through materials. You can find a DVD disk burner at most electronics stores.

If you can't get your hands on this one, you can also use a BluRay burner as it will serve the same purpose. The only downside is that it will be a bit more expensive. But if you want to save some money, this is a great option.

Keep in mind that you will need a power supply for your laser as well. This can be easily found at any hardware store. Make sure to get one that is compatible with your DVD disk burner. 


You will, of course, need to power your laser. This is most commonly done with batteries. The size and type of batteries you'll need will depend on the make and model of your laser, so be sure to check your user manual before purchasing batteries.

For example, some lasers may require AA batteries, while others may require a more specific type of battery.

If you're not sure which batteries to buy, you can always contact the manufacturer of your laser directly and they will be able to advise you on the best type of batteries to use.


You'll also need some tools that are probably already down in your garage workshop. For example, screwdrivers will come in handy for opening up the casing of your tools so that you can access the parts inside. You'll also need gloves to protect your hands from the heat generated by the lasers. And finally, you'll need a way to focus the laser beam, which can be done with a lens or a mirror.

All these will be available at your local hardware store, so just ask the staff for help if you're not sure what to get.

Making a laser isn't too hard, especially when you gear up beforehand. You'll want to find good diodes and a driver circuit as well. Make sure to look for a good solder as well as a soldering iron that's compatible with the first two items. Get a DVD disk burner for the beam and make sure to have batteries on you to power the device. Finally, you'll also want to gather some tools to make the process smooth!
