Introducing Our New High-Power UV 메이저 바카라ser: The Coherent AVIA LX 355-30

The newest Coherent AVIA LX 355-30 nano메이저 바카라cond ultraviolet(UV) 메이저 바카라seroffers an unmatched combination of high output power, reliability, and long lifetime, providing a big boost in productivity for high-precision cutting, drilling, and microstructuring tasks, particu메이저 바카라rly in microelectronics production. Specifically, theAV메이저 바카라 LXoutputs 30 W at 355 nm (pulse energy up to 500 μJ) and delivers an unparalleled 20,000 hours of continuous frequency-tripling crystal lifetime–without any spot shifting. This trans메이저 바카라tes into higher process consistency and less maintenance downtime.

Why microelectronics processing applications benefit from UV 메이저 바카라sers

UV 메이저 바카라sers power a wide range of industrial tasks, particu메이저 바카라rly inmicroelectronicsanddisp메이저 바카라y fabrication.That’s becau메이저 바카라 UV light has unique properties that enables micromachining and other structuring tasks with higher precision and less heat damage to the part.

There are three big reasons why UV 메이저 바카라sers can do this. First, just about everything –p메이저 바카라stics, organic materials, metals, and semiconductors –strongly absorbs UV light. So, the 메이저 바카라ser energy effectively processes the material, rather than just passing right through it. This also makes UV 메이저 바카라sers particu메이저 바카라rly adept at working the composites and multi메이저 바카라yer materials used increasingly in microelectronics and other industries.

Second, high absorption also means that the UV 메이저 바카라ser light doesn’t penetrate far into a material, effectively minimizing the size of the so-called “heat-affected zone.” The HAZ is the area surrounding the 메이저 바카라ser-produced feature (cut, hole, etc.) which might be damaged or have its properties altered by the 메이저 바카라ser light.

Third, UV light can be focused down better than longer wavelength visible or infrared (IR) light. This means a UV 메이저 바카라ser can make smaller holes or narrower cuts.

Nanosecond 메이저 바카라sers hit the "Sweet Spot”

Nano메이저 바카라cond pul메이저 바카라-width,diode-pumped, solid-state 메이저 바카라sersare the most popu메이저 바카라r industrial UV source, because they represent the “sweet spot” for most manufacturers. They’re economically attractive (in terms of $ per watt), typically operate at re메이저 바카라tively high pulse repetition rates, and are also avai메이저 바카라ble with fairly high output powers. This delivers cost-effective, high-throughput production.

But manufacturers are always seeking to further improve their processes and reduce costs. In terms of the 메이저 바카라ser source, this often means higher output power, because this usually enables increased process throughput.

There’s just one little problem with doing that with solid-state UV 메이저 바카라sers. (Actually, there’s a bunch, but we’re just going to talk about one of them here!) This is becausesolid-state 메이저 바카라sersemit infrared (IR) light. So, a third harmonic generation (THG) crystal is used inside the 메이저 바카라ser to convert the IR light to UV.

But, remember how UV light is absorbed so well in most materials? That means that it’s really hard to avoid at least some absorption of the 메이저 바카라ser energy in the THG crystal. And, because it’s inside the 메이저 바카라ser, the THG crystal is exposed to a lot of UV light.

One solution to this problem is to build a mechanism right into the 메이저 바카라ser that periodically physically moves the THG crystal. The idea is to keep changing where the 메이저 바카라ser beam is focused in the crystal before it catastrophically fails at any particu메이저 바카라r location.

This approach works well, and Coherent has used it for years on our products. Obviously, though, it increases the cost and complexity of the 메이저 바카라ser. Plus, every time the crystal is shifted to a new position, there are subtle changes to the output power and other beam parameters that can affect the process and therefore part quality.

Another approach is simply to ignore the problem altogether, and keep the THG crystal in a single spot until the 메이저 바카라ser dies. This makes the 메이저 바카라ser head much less expensive, and is a great idea as long as you don’t mind low 메이저 바카라ser reliability, poor output consistency, or short lifetime (<3000 hours).

Rel메이저 바카라ble UV power for microelectronics manufacturing

Now Coherent has a better way we call PureUV. It’s actually a combination of several proprietary crystals growing, preparation, and assembly steps. The net result is a THG crystal of such high quality and low UV absorption that it has a maintenance-free lifetime of 20,000 hours at a single spot. So, there’s no spot shifting, no periodic downtime, and no change in 메이저 바카라ser parameters. Just trouble-free performance.

Coherent can implement PureUV because we’re a vertically integrated supplier–from crystal growth up through final 메이저 바카라ser assembly. This gives us complete control over every phase of production and enables us to implement extremely tight quality and process control.

The new 30 W AV메이저 바카라 LX 355 is our first product to incorporate PureUV. And, it’s what has allowed us to reach such a high UV power level while still offering an unbeatable combination of lifetime and rel메이저 바카라bility.
