laser DPSS
This document outlines the transformation of a basic, cost-effective green laser pointer into a laboratory-grade laser. The core of this diode-pumped solid-state (DPSS) laser is an affordable green laser pointer. These pointers are essentially DPSS lasers that include a small...
Home-Built Carbon Dioxide (CO2) Laser
The carbon dioxide (CO2) laser serves as a critical tool in high-tech industrial applications such as cutting and welding various materials, including metals. Smaller CO2 lasers are utilized for marking metals, wood, and composites, as well as in medical and...
Optical Pulse Generator
This device was originally designed to test the Shutter Time Meter, which is specifically intended for analog SLR cameras. To accurately measure a camera's exposure time, it must first be checked with a well-defined signal. This circuit serves that purpose...
Laser Alarm fun stuff
One day, an individual contemplates the necessity of purchasing an alarm installation system when it is possible to create one independently. The common rationale against this is a lack of skills or time. However, in this case, the preference leans...
Free-Air Laser Light Communications
Due to the high frequency of light within the electromagnetic spectrum, it serves as a superior medium for communication compared to radio waves. Lasers are ideal for communication links because they produce a powerful and narrow beam that is minimally...
measurement Measuring large differential voltage
A high voltage power supply is designed for an electron beam system. The voltage regulator utilizes an outdated analog system that operates through a comparator and a reference signal from a potentiometer (POT). The challenge involves the feedback voltage from...
converter 220v ac to 40kv ac
The step-up transformer described can be repurposed as a flyback transformer from an unused television. It is advisable to utilize a basic model without a voltage tripler or high-voltage diode. This type of transformer is capable of generating voltages up...
laser trip wire circuit
A replication of the Afrotechmods laser tripwire circuit utilizing a simple laser pointer, an IRF244 MOSFET (most NPN transistors would also suffice), a few resistors, and one light-dependent resistor (LDR).
The Afrotechmods laser tripwire circuit is an innovative application of basic...
Laser Microphone
This project was a final assignment for an optics class (EE 134) at Stanford University. It was an open-ended task aimed at creating a fully functioning laser microphone. The class focused on demonstrating optics and photonics in the laboratory rather...
