Laser diode basics
Laser diodes are specialized optoelectronic components that are available in a wide variety of specifications. They are designed for emitting coherent illumination within specific wavelength bands. They are extremely useful devices for creating effective structured light solutions. However, these components are very complex and require a deep understanding of their working principles in order to manage their wide tolerance spectrums and their sensitivity to current spikes & ESD.
Osela’s decades of experience in the laser industry has allowed us to develop highly optimized laser diode driver electronics for optimal performance and reliability. Our in-house manufacturing capabilities enable us to tailor our drivers to specific laser diode electronic characteristics. Features such as active constant power feedback loops, overcurrent/overvoltage and IEC required single fault protections are integrated into all of our platforms. Our optical manufacturing capabilities allow us to adapt beam shaping to each laser diode’s specific optical signature.

Laser diode lifetime and reliability
Operating temperature, optical power setting and duty cycle are all factors that play an important role in laser diode reliability and lifetime. Understanding these parameters in detail enable us to provide our customers with the best performance recommendations for their application. Osela can provide statistical lifetime estimations specific to customer operating conditions, derived from MTTF data provided by laser diode manufacturers as well as our own internal lifetime testing. This emphasis on reliability is a fundamental key strength of the company.

Laser diode sourcing
Laser diode sourcing can be challenging, as they were originally developed for high volume commercial applications (DVD, Blue-Ray, diode pumping, lidar, barcode readers, printing etc). Over decades of experience in the industry, we have developed extensive knowledge as well as close partnerships with our laser diode suppliers that guarantee quality and repeatable supply. Osela’s rigorous internal qualification process considers all aspects of laser diode performance, lifetime, product cycle and cost, providing our customers with the needed confidence when launching a new product.

Heat dissipation
For improved stability and lifetime, it is important for the heat generated by the laser diode and its driver to be dissipated effectively. Osela’s laser products are designed to optimize heat extraction with features such as active thermoelectronic cooling and passive heat sinking strategies. Product specific thermal management recommendations are provided in order to aid our customers with system integration.
