Surface Treatment Lasers

What are Surface Treatment Lasers?

Surface Treatment Lasers

Lasers are utilized in a wide variety of different surface treatment applications in modern manufacturing and materials processing.  This application space encompasses a wide variety of diverse processes, ranging from surface heating applications such as cladding and laser cleaning to thermal ablation applications like engraving and marking.  As a result, the lasers required for such applications are also extremely diverse.  For example, laser cladding involves the use of extremely high powered laser diode stacks, coupled with either a focused jet of powdered material in a buffer gas coincident with the cladding laser spot or by depositing the material on the surface first and then scanning over it with the cladding laser.  By contrast, laser texturing uses q-switched laser pulses to engrave the negative image of a design into a mold to produce an end product with a raised decorative patterned surface.  Perhaps one of the most unique laser surface treatment applications is lithography, which is widely used in the semiconductor industry for etching nanoscale structures into wafers, transferring shapes from a photomask to the wafer using ultraviolet light by UV lasers.  On this page, you will find a list of all of the surface treatment lasers we offer at RPMC.

JOLD-Stacks Series

The JOLDStacks Series offers a highly modular approach for power scaling well into the kW-range through vertical stacking of individual sub-mounts within multi-laser-bar packages. Our optimized beam quality (BPP) is achieved through our unique approach of reducing the pitch of neighboring stacks without compromising cooling capacity. Our proven hard-solder technology and strictly monitored production processes ensure tried & tested reliability under even the harshest environmental conditions. The series also features microchannel-cooled packages for CW-operation, actively cooled with deionized (DI) water. 

RPK Series

The RPK Series of multiple, single-emitter fiber-coupled diode lasers are available in wavelengths from 405nm thru 1550nm with up to 300W output power. Our specialized fiber-coupling techniques ensure high efficiency, stability, and superior beam quality, while rigorous inspections and burn-in procedures guarantee each product’s reliability, stability, and long lifetime. Highly customizable packages allow us to meet our customers’ specific needs, providing high-quality products at reasonable prices. 

VaryDisk Series

VaryDisk E150The VaryDisk Series is a high-energy, multi-milli-Joule laser system suitable for laboratory investigations or industrial use. This thin disk regenerative amplifier can amplify femtosecond, picosecond, or nanosecond pulses with amplification factors up to 10⁶. With a range of output specifications to choose from, including multiple seed lasers, customers can select the ideal configuration to meet their needs. The base configuration offers up to 150 W average power @ 1030 nm, 15 – 150 mJ pulse energy, 1 ns pulse width (compressible to < 2 ps), and a repetition rate range of 1 kHz to 10 kHz.
