Laser Diode Analyser

A recent addition to the line-up is the World Star Tech Laser Diode Analyser, designed for laser parametric analysis, generating high resolution LIV ( light, current, voltage) curves in seconds and revealing diode parameters such as threshold current and slope efficiency.  The results can be viewed on the built-in touchscreen interface and the system can be connected to your computer to download and process the data. The high performance smart driver automatically detects your laser diode pinout and can drive the laser diode in auto-current or autopower control modes. The integrated TEC controller maintains the diode under test at its operating temperature ensuring accurate and repeatable measurements. Multiple levels of laser diode protection include adjustable current limiters, automatic pinout detection, and frequent sensor range checks. Passcode-protection prevents the system from being used by unauthorised personnel. Multiple operator roles allow a manager to lock in system parameters, eliminating the risk of accidentally changing settings which could damage a diode or invalidate results. Hardware interlocks can be connected to disable the laser if desired. Included with the system is a calibrated optical power meter and a thermally controlled laser head for 5.6 mm package laser diodes. A sliding quick-change mechanism makes it easy to exchange laser diodes between tests. 3.8 mm and 9 mm package laser diode laser heads are available upon request. Custom connectors to test butterfly laser diode packages and user designed laser heads can also be used.

Compact Laser Diode Modules

In addition to the Laser Diode Analyser, ALRAD provides a range of Compact Laser Diode Modules including: NIR, Visible Red, Blue, Green, Violet and RGB wavelengths, Laser Line generators, Uniform  line Lasers, cross line lasers and computer controlled Laser systems.
