Laser torch schematic
The laser torch is an economical device with impressive cost-performance characteristics. Its primary feature is the exceptional performance of the condenser, allowing for an optical range of 1200 to 1500 meters. The beam remains focused and small even at distances...
Cool Electronics main page
This laser is constructed on a polystyrene sheet. An aluminum foil layer acts as a ground plate (-), which is important for preionization. After that, the dielectric is placed on it, leaving 1 cm from each border of the foil....
toy laser gun
A broken RC car remote shaped like a pistol was discovered in a toy box, leading to the idea of modifying it into a toy laser gun. A cheap laser pointer was also available for the project. Unfortunately, pictures of...
LASER Transmitter/Receiver
This set of two circuits forms the basis for a very simple light wave transmitter. A LASER beam is modulated and then aimed at a receiver that demodulates the signal and then presents the information (voice, data, etc.). The whole...
Diode Sensor For Lasers
Laser-receiver circuits must bias their avalanche photodiodes (APD) to achieve optimal gain. Unfortunately, an APD's gain depends on the operating temperature. The circuit controls the operating voltage of an APD over a large temperature range to maintain the gain at...
Home-Built Nitrogen (N2) Laser
The nitrogen (N2) laser generates extremely short pulses of light (lasting a few nanoseconds) with a typical intensity of 100 kW in the near ultraviolet (UV) range of the electromagnetic spectrum, specifically at 337.1 nm. Despite its impressive capabilities, the...
Help with Laser Alarm Circuit
A new user has recently discovered a Laser Alarm System and has decided to explore this project.
The Laser Alarm System is a security device that utilizes laser beams to detect unauthorized entry or movement within a designated area. The fundamental...
Laser Data Link schematic
This document tells about one of my experiments with semiconductor laser modules. I bought one semiconductor laser for all kinds of experiments. This TIM202 module is a small (38x14x14 mm) semiconductor laser module, similar to those types used in laser...
Laser Door Alarm Circuit
This laser door alarm operates by detecting the interruption of a laser beam. A low-cost laser pointer serves as the light source. When an individual crosses the path of the laser beam, it triggers the alarm.
The laser door alarm circuit...
