Thank you, Joe. Starting on the slides 3 and 4. 2021 was an important year for nLIGHT. Year-over-year growth in each of our end markets enabled us to generate record annual revenue of $270 million. Overall revenue in 2021 grew approximately 21% in line with our long-term compound annual growth rate of 23%. To put that in perspective, total revenue was nearly double what we generated in 2017, the year immediately prior to our IPO. We continued to execute on our strategy of increasing sales to industrial customers outside of China and in aerospace and defense. Over the long term, we continue to believe that we can meet or exceed our historical revenue CAGR of 20% and product gross margins of 40 plus percent. To meet these long-term objectives, we will continue to invest in automated capacity in the U.S. and optimize our manufacturing footprint in China. While this important operational transition will result in pressure on our gross margin and operating margin for the next few quarters, as we look beyond 2022, we believe it will enable us to achieve higher levels of profitability as we scale to address anticipated robust customer demand. Turning to Slide 5. 2021 was an important year for our transition in our geographic focus. Our results illustrate how our business has evolved since our IPO in 2018. In just a few years, we've migrated from a strategy that had included significant focus on both operations and markets in China to a strategy that is primarily focused on both operations and markets outside of China. In 2021, revenue from customers outside of China grew 41% year-over-year to approximately $215 million, which represented approximately 80% of our total revenue. Turning to slide 6. In Q4, revenue from customers outside of China grew by 26% year-over-year to approximately $60 million or 89% of total revenue. We have doubled our revenue outside of China since Q4 2019 and for the first time since we went public in 2018, all of our top 10 customers were from outside of China. While our geographic focus has transitioned, our strategy remains focused on leveraging our vertically integrated business model to enable key growth markets. Slide 7 provides an overview of our vertically integrated business model that begins at the semiconductor chip level, where we produce high-brightness, high-power laser diodes. Over time, we've extended our technology stack into fiber-coupled semiconductor lasers, optical fiber, and fiber lasers. A deep understanding of each of these technologies and improvements across this vertical integration enables us to design products that are optimized for specific applications. With the acquisitions of Nutronics in late 2019 and Plasmo earlier this week, we further expanded our technology capabilities to include beam control for both defense and industrial applications. Our ability to direct, adjust, monitor, and control the laser beam enables us to attract the most efficient and economical use of energy from our lasers. We believe that broad adoption of lasers will increasingly require integrated lasers with beam control to continue the displacement of legacy technologies. In addition to our continued expansion of differentiated products, we are well positioned to capitalize on multiple attractive long-term growth opportunities. And in 2021, our revenue grew in each of our end markets. Turning to Slides 8 through 10, where I will discuss each of these markets further. In microfabrication, we had a strong year, with 36% year-over-year growth. Our industry-leading high-power, high-brightness semiconductor lasers are often the critical enabling component of our customers ' products. As laser-based manufacturing processes continue to proliferate, we believe we will continue to benefit from wider adoption and a range of applications in the automotive, consumer, communications, electronics, display, medical, and semiconductor end markets. In Q4, the demand environment in Microfabrication remained strong and grew -- we grew revenue approximately 34% year-over-year to $17.3 million, representing 25% of total revenue. In Aerospace and Defense, our revenue grew 21% year-over-year in 2021 to a new record of $105 million, representing 39% of total sales. 2021 marked the fifth consecutive year of annual A&D revenue growth. We saw relatively consistent demand for our core long-term A&D customers and programs throughout the year, and we believe there are many additional long-term opportunities for our laser technology. Although new programs often take time to develop, we believe that we are well-positioned for future long-term growth in this part of our A&D business. We were also pleased with our progress in direct energy, as we achieved several critical technical milestones during the year. We're one of four award winners of the High-Energy Laser Scaling Initiative, HELSI for short, which is a U.S. government program to develop a 300 kilowatt laser. Although the timing of future programs of record is not yet clear, we remain steadfast in our belief that directed energy will be a key part of the United States military modernization efforts. Our vertically integrated business model, coupled with our deep understanding in work in defense, positions as well for future success in this market. In the fourth quarter, our defense revenue declined approximately 1% year-over-year to $28.5 million, representing 42% of total revenue. Development revenue, nearly all of which is related to directed energy projects increased approximately 18% year-over-year, but was lower than our quarterly guidance due to supply chain issues. Finally, turning to the industrial end market, industrial revenue grew 12% year-over-year in 2021. More importantly, industrial revenue from customers outside of China increased 66% year-over-year. In the fourth quarter, while overall industrial revenues declined 9% year-over-year, revenue from industrial customers outside of China increased by 57% year-over-year to $18.7 million and nearly doubled versus the same period in 2019. On a percentage basis, Q4 industrial revenue from customers outside of China increased to 86% versus 50% in the same period of 2020. This growth outside of China was driven by continued expansion of strategic customers in cutting, welding, and additive manufacturing. As we have discussed, we have prioritized deep engagement with these customers, and many of our current design wins took multiple years to secure and we believe serve as a strong foundation for future growth. In Cutting, we saw continued adoption of our programmable and high-power lasers in leading machine tool manufacturers in U.S., Japan, Korea, and Europe. In Welding, we continue to see long-term opportunities, especially in electric vehicles. Our programmable lasers coupled with new software and sensor technology we acquired via the Plasmo transaction, will support continued customer engagement and long-term opportunities in this market. Finally, in metal additive manufacturing. We saw significant increase in customer engagement, design wins, and sales of our additive manufactured specific lasers. We believe this market is at an inflection point as multiple laser tools combined with further improvements in our programmable lasers will further drive improvements to displace legacy machining and casting. I will now turn the call over to Ron to discuss nLIGHT's full-year and fourth quarter financial results.
