Heat Treating with High Power Diode Lasers by Keith Parker, Sr. Business Development Manager – Direct Diode & Fiber Laser Systems Carbon dioxide (CO2) lasers have been used in heat treating for over 30 years, as an alternative for induction or other traditional heat treating techniques. In the millisecond range, laser heating is used to measure thermal diffusivity and heat capacity of materials in the solid and liquid phase near the melting point.

In the microsecond range, pulsed laser heating is used to obtain thermophysical properties of high melting materials, such as those used in nuclear reactors.

• Device Heat Load In many applications, In many applications, such as diode-laser temperature control, the device being cooled (or heated) produces heat itself. For example, a typical 3 mW diode laser will produce about 90 mW of heat when operated at room temperature.

Under similar conditions, a mW diode laser produces about mW of heat. SURFACE has developed a laser heating system for substrate sizes of up to 15×15 mm 2, using the latest available diode laser technology with powers from W to W, which avoids the problems of conventional heaters mentioned above.

Clearly, a complete treatment of all laser surface modifications and applications is beyond the scope of a single book chapter, so we will primarily focus on two specific case studies in which new applicationsare actively being delving into these case studies, we start with a short review of the underlying prin- ciples and equations governingthe absorption of laser light and the transport of heat.

This book discusses the heating of metals by laser beams at intensity levels too low, or radiation times too short, to cause target material ablation and plasma formation near the metal surface.

The specificity of this approach to the topic rests with the factors governing heating kinetics. Laser heating and resistance heating are two heating methods that are commonly used in heat-assisted microforming processes. Laser radiation provides the most suitable choice for the purpose of heating the material during microforming process as it offers several advantages in comparison to other methods, including [35]: (1) the laser energy input and thus the resulting temperature in the.

The book reaches from the basics to advanced topics of pulsed laser ablation. Theoretical and experimental fundamental phenomena involved in pulsed laser ablation are discussed with respect to material properties, laser wavelength, fluence and intensity regime of the light absorbed linearly or non-linearly in the target material.

Laser heat treating, also known as laser hardening, is a surface modification process used to increase wear resistance or extend the lifetime for items ranging from household tools to parts in automobile manufacturing and tooling in heavy industry and transport sectors.

Laser hardening is most commonly used for steel and cast iron materials. The State of the Art in High-Power Laser Technology. Filled with full-color images, High-Power Laser Handbook offers comprehensive details on the latest advances in high-power laser development and applications.
