4 Industrial Laser Applications for Direct Diode Heating

In our recent direct diode heating blog series, we expressed some of the advantages of direct diode heating, which refers to heating specific regions of a material’s surface using diode lasers. As described previously, direct diode heating provides a number of benefits over traditional methods of indirect heating, such as heating lamps. These advantages include:

8 Design Considerations for Direct Diode Heating Systems

Direct diode heating in industrial applications refers to heating specific regions of a material surface with a semiconductor laser diode. This is as opposed to a fiber or solid-state laser or other non-laser heating methods. In a previous article we described reasons why direct diode heating is more effective than older methods such as IR lamps, microwaves, or forced air. One of the primary advantages of diodes is their flexibility—virtually any aspect of a diode laser heating system can be designed and optimized for performance and cost. Below are 8 factors to consider when choosing a laser diode for a direct diode heating system.

Medical Diode Design: Multi-Wavelength Diodes for a Broad Spectrum of Customers

Companies are finally recognizing what medical laser manufacturers have known for years: there is no single color of “skin tone.” In cosmetics, skin care, and clothing, companies are broadening their spectrum to broaden their customer base. Matching a skin color is difficult because there is no simple way to define what a "skin color" even means. An object's "color" is a complicated mix of the spectrum of the incident light and how that object absorbs and reflects that light. At present, skin colors are described using the Fitzpatrick scale, a qualitative method based on the light-absorption features of the skin, which determine both the skin's apparent color and its propensity to sunburn. It's important to also remember that skin is a living thing that changes thickness, color, and texture, depending on age and environment.

Four Reasons Dollars per Watt Is the Wrong Metric When Choosing Diode Pumps for High-Power Lasers

For all laser applications, including commercial and defense, a primary objective is to maximize performance while minimizing cost. Within the telecommunications industry, a common metric when selecting a laser diode is the cost of the laser divided by the power of the emitted light—dollars per watt. Although dollars per watt is an effective metric for commercial applications, it is an oversimplification when designing the optical pumping system for a high-power laser, especially for military lasers, for several reasons.

Five Sources of CW Laser Diode Failure and How to Prevent Them

Continuous Wave (CW) laser diode arrays are principal components of modern medical, automotive, and defense equipment. As such, the reliability and longevity of the instruments rest upon the reliability and longevity of the laser diode array. This article describes five common causes of failure and how to avoid them.
