2DPSS Lasers Inc. – Santa Clara, CA DPSS Shanghai(Pudong)
3DPSS Lasers Inc - History Since 1972, DPSS and our former company LiCONiX have been building UV laser systems.As LiCONiX, we delivered over 25,000 Blue and UV HeCd gas lasers.Sold LiCONiX’s gas laser group to Melles Griot in Spun-off the engineering and solid state laser group to form DPSS Lasers Inc.Many current DPSS employees were managers or senior employees of LiCONiX.Same Board of Directors as the former LiCONiX, with the addition of Alex Laymon.
4Why DPSS Lasers IncWe specialize in the manufacturing of DPSS UV lasers. This is our only product.We are the world’s largest supplier of DPSS UV lasers in StereoLithography.Because of our volume and efficient design, we are the low-cost leader for UV systems around the world.
5Why DPSS Lasers IncPatents - We hold patents on DPSS IntraCavity UV lasers in US, Japan, UK and Germany (US PAT# 6,002,695)Over 1600 DPSS UV lasers have shipped and are in use in 23 countries.Developed first DPSS IntraCavity UV laser in Shipped first DPSS UV laser in 1998.
6Why DPSS Lasers Inc We ship 5 to 15 DPSS UV lasers per week. We keep 30+ UV lasers in stock at all times.Most orders for new or service lasers ship same day.
7Why DPSS Lasers Inc Over the years, many top-tier, Global companies have relied on DPSS Lasers Inc. to process their materials.GentexHoneywellIntelAppleLockheedMolexPPGRoushSiemensIBMTexas InstrumentsAbbott Labs3MMedtronicBoeingSonyUS ArmyBaxterDelphiFordGM3D Systems
8Customer Application – Does it Need a Laser? Need to Get Rid of Labels, Ink, Glue –Lack of DurabilityCannot CleanContamination ReasonsShort term ConsumablePricing per piece is too highPrecisionNeed Fine Features or High DPIPermanent – Security. No Changing.Need for an Eco-Friendly Process
9Laser Application – IR versus UV Lasers IR Lasers – These lasers mark by heat and thermal changes of materials.CO2 – wavelength 10,600 nm. Least expensive. All marks done by heat with material damage. (Paint Sprayer)Solid State – wavelength 1064 nm. Moderate costs, with good life. Marks done with heat with 10X smaller spot than CO2. (Paint Roller)Fiber Lasers – wavelengths nm. Moderate costs, with long life. All marks still with heat, and slightly smaller spot sizes.UV Laser – Lasers mark by Photo-chemical changes and/or photo-ablation of materials.Wavelength of 355 nm. Slightly higher cost with good life. (Painting with fine tip brush) The advantages of UV lasers are minimal heat effected zones and smaller feature sizes. (30X smaller spot than CO2)UV lasers are often referred to as “Cold Lasers.”
10Why UV versus IR LasersApplications that were previously inaccessible to laser technology are also opening up with the aid of UV DPSS lasers.IR marks on many plastics are controlled melts with variable contrast.UV marks are usually high contrast, with minimum or no damage due to the photochemical effect of the UV photon on the material in process.Lower Power levels needed - A 10 um dia, 1 Watt UV beam has same power density as a 100 um dia, 100 Watt CO2 Laser
11Why UV versus IR UV Mark on left, IR mark on right. Notice clean sharp IR mark is unevenedge of UV Mark and melted
12Will UV benefit my application? DPSS Lasers Inc has a free applications lab in Santa Clara CA.The customer can either send their samples or visit in person to evaluate the UV difference.If a picture is worth a thousand words, an actual UV-processed sample is worth a thousand pictures.DPSS Lasers encourages the customer to send your samples and your NDA.
14Samurai UV MarkerFirst laser marking system specifically designed for UV lasers.Takes advantage of the short UV wavelength to provide a small spot size and a large depth of focus.Takes advantage of the “cold” marking process not requiring high average powers and allowing damage free marking on many materials.

25UV Laser Success Stories Medical Device Company 1 - Heart ImplantSkiving insulation from 200 um wire for lead attachment.Medical Device Company 2 - Multiple systemsMarking plastic devices Conventional printing and labels do not hold up to continuous cleaning.Energy Company – Fuel/Energy Cell productionDrill tens of thousands of holes in thin membrane.181 Engineering – Contract Development in Silicon Valley.Remove Teflon coating from tips of neurological probes.NanoDynamics – Material StudiesAblate materials in vacuum chamber for research.
26UV Laser Success Stories Company A - Major glass and film manufacturingSamurai base mounted over production line for making film on the fly.Gentex- Automotive applicationRemove thin-film metallic coatings from backside of rearview mirrors.Medical Device Company 3 - Biomedical ImplantSamurai to remove epoxy coating from contact leads of sub-millimeter device. No damage to device.Wire marking for Commercial and Military Aircraft.In spring of 2006, FAA mandated that all wires in M&C aircraft must be marked with UV laser or each mark must be tested and certified post process. Permanent mark and no damage.Worldwide Laser - Major cosmetic company switching over from CO2 to UV due to better and faster marking of many plastics.

31General Laser Safety Eye Safety UV Beam – Cannot see, unless it hits something!!Wear Eye Protection – YesExtra Care when wearing eye protectionSkin Protection – Not needed.Electrical Safety – This is biggest risk.Solid State Lasers – Low voltage, high current. Less risky, but still up to 700 Watts.Fire Risk – Solid State Laser output can ignite paper and plastic materials – Be Careful.
