Laser Diode Drivers (LDD)
-
LDD technology has evolved from driving DVD/CD/Blue-ray optical drives to include laser projection in smartphones, automotive head-up displays (HUDs) and pico projectors. Renesas has developed new LDDs for RGB scanning laser projection systems and laser-based pico projectors. Automotive HUDs are benefiting from big innovations in MEMS projection systems and are now central to advanced driver assistance systems (ADAS) and safety. The latest laser scanned-MEMS projection systems can provide higher resolution images and at a lower cost.

Current Pulsers and Laser Diode Drivers (Pulsed Current)
-
These instruments generate current pulses whose amplitude is largely independent of the load voltage. This makes them ideal for pulsing device whose voltage may vary with time (for instance, the voltage drop of laser diodes may vary with temperature, or explosive squibs which change impedance during ignition). This voltage independence is a trade-off with speed. If faster rise times are required, consider using pulsed voltage instruments instead.

High-power Laser Diode Assembly
-
The laser diode is one of the most common devices used throughout photonics. The micro-assembly process calls for the placement and bonding (align-&-attach) of single emitters, or multiple laser diodes (stacked or complete bars), the placement, active alignment and bonding of necessary micro-optical elements, subsequent device testing, and ultimately packaging and quality control. ficonTEC’s machine systems are capable of all the steps necessary for assembling laser diodes, even high-power devices. Multiple in-line systems can be configured to address entire process segments.

Artifex Engineering GmbH & Co. KG
The LDD100 employs a digitally programmable analogue end stage for flexible and accurate current control. Currents of up to 600A with pulse durations of 50ns to 3s are generated with rise and fall times of 70ns (F-version) or 600ns (XL-version) – essentially without overshoot. Due to the flexibility in setup and control, the LDD100 is practical for many laboratory applications. For automated measurements, the unit may be directly controlled via the USB interface. Alternatively, all parameters may be input via the graphical software or via the integrated keypad and OLED display.

LIV – High-power Laser Diode Testing
-
An important aspect of the development and manufacture of laser diodes is the so-called laser diode characterization, or laser IV curve. By applying increasing current to the laser diode so it that emits light, the optical output is measured together with the voltage drop across the diode element. The resulting LIV curve reveals important clues about the quality of manufacture and the performance of the laser diode, enabling a pass/fail decision to be met.

Optical degradation of the laser diodes is observed and recorded by precisely measuring changes in the laser's operating characteristics during the test. Life-tests are used for vendor qualification of the laser diodes during product development and can be conducted throughout the production life of the laser.

Laser Diode Burn-In Testing
-
Laser reliability testing consists of a series of tests that laser diodes can be put under in order to ensure their reliability for post-production use. There are different types of tests that can be carried out and there are multiple measurements that can be taken in order to evaluate the reliability of the device. One of these tests is laser diode burn-in.

Integrated Laser Controller
ILC

AOSense has developed a compact Integrated Laser Controller (ILC) that can be paired with our External Cavity Diode Lasers (ECDLs) to control laser current, piezo transducer (PZT), and temperature. The ultra-low noise electronics are fully digitally controlled. The ILC dimensions are only 5″x2.9″x0.95″. We provide software with an easy-to-use graphical user interface (GUI) that can control multiple lasers from a single window. If preferred, commands may be sent over a USB virtual COM port. The software screenshot below (click the image to enlarge) shows the interface including a plot of the temperature (green line) as it settles to a commanded value.
