Photonics stocks are on fire — up more than 60% in some cases — as AI data center demand spills into laser optics. AI is finally nesting your parts better than a human can. And Chinese laser exports are accelerating despite tariffs. Here is the late June 2026 picture.
Photonics Stocks Rally 32-65% — AI Demand Spills Into Laser Optics
The biggest story this month might not even be about lasers cutting metal. It's about lasers moving data. Photonics stocks have been on a tear — IPG Photonics is up 64.8% year-to-date, Coherent is up 42%, and Lumentum is up 38%.
What's driving it? AI data centers need optical interconnects. The bandwidth requirements for GPU clusters are growing faster than copper can handle. And the first dedicated photonics ETF — the Corgi Lithography & Semiconductor Photonics ETF — launched in May and pulled in $261.7 million in its first few weeks.
Honestly, I did not see this one coming. I have been watching industrial laser markets forever, and the crossover between AI infrastructure and laser optics caught me off guard. But it makes sense — the same optics technology that goes into fiber laser resonators also goes into data center transceivers. IPG, Coherent, and II-VI all share the same supply chain for high-power diodes and fiber couplers.
Here is the practical angle for metal fabricators: if photonics demand keeps pulling diode supply toward data center applications, we could see lead times on laser diodes stretch and pricing edge up in Q3-Q4 2026. Keep that in mind if you are planning a year-end equipment purchase.
| Company | Stock Ticker | YTD 2026 Return | Primary Laser Exposure |
|---|---|---|---|
| IPG Photonics | IPGP | +64.8% | Industrial fiber lasers (cutting, welding, cleaning) |
| Coherent Corp. | COHR | +42% | Industrial lasers + datacom optics |
| Lumentum | LITE | +38% | Datacom optics + industrial diodes |
| nLIGHT | LASR | +32% | High-power semiconductor lasers |
AI Nesting Software Hits Production — 22% Scrap Reduction Reported
This one is more nuts-and-bolts but honestly might matter more for day-to-day shops. AI-powered nesting software is finally delivering on promises that algorithm-based nesting has been chasing for years.
Early adopters are reporting an average 22% reduction in scrap rates compared to traditional nesting algorithms. The AI models do three things differently:
- They optimize across multiple sheets simultaneously instead of one at a time
- They account for real-time material defects — if a sheet has a surface scratch in one area, the nesting avoids putting critical parts there
- They learn from your actual cut quality feedback over time
For a mid-sized shop running 500 tons of steel sheet per year, 22% less scrap translates to roughly $35,000-50,000 in annual material savings. The software typically costs $8,000-15,000 per year on top of existing CAD/CAM licenses. ROI is under six months for most shops.
I talked to a production manager at a shop in Ohio two weeks ago. He said their AI nesting system paid for itself in four months. "The first week I was skeptical," he told me. "By week three I was annoyed we hadn't done it two years ago."
Most major laser machine makers — including Han's Laser, Bodor, and Penta — now offer AI nesting as either a built-in feature or a paid upgrade on their fiber laser cutting machines. If you are buying a new machine, ask about it. If you already have a machine, check if your CAM vendor offers an AI nesting module.
Chinese Laser Equipment Exports Accelerate to 28% Growth YTD
Chinese laser equipment exports grew approximately 28% year-to-date through May 2026, accelerating from the 24% rate reported through April. Fiber laser cutting machines remain the biggest export category by value.
Regional picture is shifting a bit:
- Southeast Asia: up 38% (Vietnam +45%, Thailand +36%, Indonesia +32%)
- Middle East & Africa: up 31% — Saudi Arabia and UAE are the biggest buyers, mostly for structural steel and pipe cutting
- South America: up 24% — Brazil leads, with growth in automotive subcomponents
- Europe: up 11% — growth is steady but slowing as some buyers shift to locally-assembled machines
- North America: up 6% — tariff uncertainty is holding back bigger gains
I have been watching this shift for a while. The interesting thing is that Europe growth slowed from 12% to 11%, but it is not because European shops are buying less laser equipment. They are buying more. But some are buying from European assembly plants that use Chinese laser sources, which gets counted differently in the statistics.
One thing that trips people up: the "Chinese laser export" number includes machines assembled entirely in China AND machines that use Chinese laser sources assembled overseas. The actual number of Chinese-sourced laser cutting heads ending up in global production is probably closer to 35-40% higher than the customs numbers show.
EU CBAM Impact: Laser Cutting Demand Gets a Mixed Signal
The EU Carbon Border Adjustment Mechanism — CBAM — entered its transitional phase in late June 2026. EU importers of steel, aluminum, and other carbon-intensive products now have to start reporting embedded emissions and purchasing carbon certificates.
The early impact on laser cutting equipment demand is mixed. Here is what I am seeing:
- European fabricators are investing in higher-efficiency laser cutting machines to reduce per-part energy costs. Fiber laser sales in Germany and Italy are up 14% year-on-year.
- But some European buyers are shifting to importing pre-cut parts from Chinese suppliers instead of cutting locally. This reduces European laser cutting demand while increasing Chinese export volumes.
- EU-fabricated steel is now 8-12% more expensive than comparable Chinese material for European buyers — and the gap is expected to widen as carbon certificate prices rise.
Bottom line: if you are a European metal fabricator, upgrading your laser cutting equipment to higher efficiency is becoming a necessity, not a nice-to-have. A modern 12kW fiber laser with AI nesting and auto loading can cut per-part costs by 25-30% compared to a 5-year-old 6kW machine, more than offsetting any CBAM-related material cost increases.
Ultra-High-Power Laser Race: Who Is Doing What at 60kW+
IPG's 60kW announcement in mid-June has not gone unanswered. Two other players have confirmed they are working on or releasing 50-60kW class systems:
- Raycus: Announced a 50kW multi-mode fiber laser prototype in late June, targeting shipbuilding and heavy construction. Production target is Q1 2027.
- Maxphotonics: Working on a 55kW single-mode system with a national research institute in China. Early field trials expected by end of 2026.
- Coherent: No confirmed 50kW+ announcement yet, but industry sources indicate they are developing a 40kW+ upgraded version of their HighLight series.
This is clearly a race where IPG holds the lead for now, but Chinese manufacturers are closing faster than many expected. The technology that drives these systems — high-brightness diode pumps, advanced beam combining, and thermal management — will eventually trickle down to mid-power systems, making 6-12kW machines more compact and efficient over the next 18 months.
Bottom line for late June 2026: Photonics is having its AI moment, and that is pulling capital into the broader laser ecosystem. AI nesting is making real production improvements today. Chinese laser exports are accelerating, not slowing. And the ultra-high-power race is getting crowded. If you're planning a capital purchase, the technology mix is better than it has ever been — but watch for potential diode supply tightness in Q4.
