Product Overview:

High Stability Blue Laser Diode Module

These modules utilize the latest technology high power blue laser diodes. Using a blue semiconductor laser diode source, these modules offer much higher power stability than a DPSS laser. Also, because of the reduction in the number of internal parts needed to produce a beam, the system is more reliable, offers higher efficiency, and an extended service life.

Microcontroller-Based Operation with Laser Safety Features

These units are microcontroller based, providing a soft start of the laser diode and also regulating the temperature. The system protects the diode from overheating: when the temperature of the diode exceeds 50°C, it prevents further current flow through the diode and goes into alarm mode.

Simple Integration with Single Power Supply

The module is powered by a single 7.5 VDC power supply, drawing up to 17 A. The laser is modulated via separate analog or TTL control signal, up to 80kHz bandwidth.

Compact, Heat-Dissipating Housing

The diode along with the entire optical system is mounted in a compact housing which ensures both protection and cooling. To enable continuous work of the module, for example in a laser projector, it must be placed on an aluminum plate which allows for heat dissipation (thermal grease significantly improves the cooling of the module). It is a solution that not only saves space in the projector cabinet, but also reduces the level from which the beam is emitted. This is aimed at meeting the demands of customers who more often than not look for compact high-power modules.
