Stainless Steel

Thu, 08 Jul 2010 11:38:45 GMT

Stainless steel is a widely used material in industries ranging from aviation and aerospace, to medical devices and surgical instruments. One important application of Raydiance's ultrafast laser platform, particularly for the aerospace industry, is that of marking small parts. Here, a 1.2 mm square, machine-readable, two-dimensional matrix was ablated in stainless steel in less than 10 seconds. The depth of the marks can be varied, depending on application needs and laser parameters.

Microfluidics Features in Quartz

Thu, 08 Jul 2010 08:46:16 GMT

Quartz is increasingly becoming the material of choice in the microfluidics field. Due to its chemical structure, quartz is naturally conducive to capillary electrophoresis (CE), a functional requirement for lab-on-a-chip and other microfluidics applications. While plastics are often used as the chip material, they require surface activation processes to establish a "charged wall" for CE. This adds to the cost and reduces the yield of plastic systems.

Platinum

Like gold, platinum is increasingly begin deployed in medical device applications. Though difficult to machine with traditional lasers, mechanical saws or electron discharge machining, platinum can be easily and precisely ablated with the Raydiance ultrafast laser platform.

Gold

Due to its radiopacity, bio-compitability, and high electrical conductivity, gold is a highly valued material for medical device applications. It is also notoriously difficult to machine. However, Raydiance applications engineers have recently demonstrated the ability to cleanly and precisely machine this noble metal with the Raydiance ultrafast laser platform.

Bioabsorbable Stents

Tue, 06 Oct 2009 22:50:06 GMT

This bio-absorbable stent with 150 um wall thickness and 3.48 mm outer diameter was machined with Raydiance Smart Light in approximately 3 minutes. There are no melt or other heat affected zones whatsoever. This part was taken from the Smart Light workstation and then was photographed without cleaning.

Raydiance Nitinol Stent

The ability to athermally ablate materials represents a significant advance in the manufacturing of medical micro-devices. Here a Nitinol stent was machined with precise features such as would be used in a commercial vascular stent design.

Nitinol tubing, much like would be used for a vascular stent, was machined with a Raydiance system. In this image, the edge detail of the cut is shown, revealing absolutely no heat affected zones. Note that the scale bar represents 10 um.

Nanostructured Silicon

Fri, 27 Feb 2009 03:34:08 GMT

This silicon wafer was nanostructured with the Raydiance ultrafast laser. Structuring of this sort has application in the photovoltaic cell market.

Pig Cornea

Fri, 27 Feb 2009 03:25:25 GMT

Sub-surface ablation was used to create a 200 um thick flap in a pig cornea, much as would be done in a LASIK procedure. The flap is folded back to the left. From its transparency, it is evident that there was no thermal damage to the tissue.

Life Sciences Glass Needle

Fri, 27 Feb 2009 02:40:54 GMT

This 120 um diameter life sciences glass needle, such as is used for in-vitro fertilization, was machined with the Raydiance platform. The hole in the side of the needle is 10 um in diameter.

Bar Code in Quartz

Fri, 27 Feb 2009 02:40:30 GMT

A bar code pattern was uploaded into the Raydiance system and then machined below the surface of a glass sample.

Tungsten

Thu, 26 Feb 2009 23:35:45 GMT

Tungsten, one of the hardest materials known, was easily machined with the Raydiance 1552-10 system. This feature is approximately 700 um deep and 276 um wide.

Titanium

Thu, 26 Feb 2009 23:32:47 GMT

Two 20 um lines were machined in this 50 um titanium sheet. Notice that at the junction of the two features there is no recast or other thermal effects.
