Most diode lasers lack a proper laser crosshair to precisely position projects on material, and in this project video, I will show you how to make your own in order to augment any laser on the market.
The discussion revolves around powering a 1064nm laser diode for a portable laser project, focusing on voltage regulation and current control
I wanted suggestions on how to power a diode or laser pointer and being able to lower and vary this voltage below that max voltage threshold. Should I used a voltage regulator and
These small lasers typically run the pump diode and crystal set at absolute maximum already. A pot mod may simply kill the pump diode. A mod is technically possible, but very very
I settled on using the Nichia NDG7475 laser diode as that is the brightest laser pointer out there that is still small enough to be jammed into a laser pointer housing.
Did you know the DVD burners that we used back in the day have laser diodes? These diodes could emit not only visible but invisible laser radiation
I''ve always wanted an extremely powerful keychain laser "pointer" so I made it happen, even if it took supercapacitors and some of the craziest laser diode tech out there.
Unfortunately we''ve had problems with designing the laser since the 1064nm diode that we were going to use for the laser gave very poor results and we have to change that part. Now I am
I have a bunch of these cheap red laser pointers, and am trying to understand how the circuit works. (And see if I can do anything fun with them, like modulate the beam or increase the
"The reason is that my mod bypasses resistors, which means lots (Max) of power entering the laser diode. The normal pod mod decreases a little resistance to allow addition current to enter
An Introduction to Laser Diodes Learn about the laser diode, including package types, applications, drive circuitry, and some laser diode specifications.
If you want to control each individual laser, you will need a switch for that laser capable of carrying the required current. You can buy ICs that contain arrays of transistor switches.
I have the 445 nm NDB7A75 laser diode, and I was hoping to use it in a regenerative amplifier, for which I need pulses. The pulses would optimally be picoseconds, but could be in the
This is the ultimate beginner''s guide to the laser diode. Learn how lasers work and how you can use them in your own projects with this guide.
I decided to modify the laser pointer housing to accept a standard 18650 battery that I had laying around the house; a relatively standard rechargeable battery among flashlight and laser
Laser Pointer: Lasers these days come in many different shapes and sizes. Building your own, you also have the option of making it almost any color laser you want.
ShillehTek5V Laser Diode: A small, focused-beam laser module commonly used in alignment systems, pointers, and various DIY electronics
This article illustrates the detection of 6 degrees of freedom (DOF) for Virtual Environment interactions using a modified simple laser pointer device and a camera.
One way to increase laser pointer output is to optimize the laser diode. Laser diodes come in various power ratings, and replacing a low-power diode with a higher-power one can
They are used in laser printers, laser fax machines, laser pointers, measurement equipment, bar-code and UPC scanners, and in high-performance imagers, as
A light-emitting diode (LED) and a semiconductor laser both generate light in the interface region between two different types of semiconductor
This video was only made because for some reason I''m constantly getting messages and comments asking how to do this. (I''m not an expert)(definitely not an ex...
Where what you really want is a working visible diode laser, a commercial laser pointer or diode laser module may be the best option. Both of these include the driver circuit and will run off of unregulated
Hey all, I''ve been lurking for a few weeks but this is my first post so go easy on me :) I''d like to use an Arduino (uno) and an optocoupler to TTL/PWM switch a ir LD (808 nm, 280 mA) which
Laser diodes are highly susceptible to damage from forward and reverse voltage surges and transients, and they require a special set of
Direct Modulation is when the current, before reaching the laser diode, is modified with the desired signal for the application. This uses a function generator to create the modulation signal and a laser
The modified laser pointer (right) projects a regular grid of points on the projection surface (left) using a cross diffraction grating.
