Industrial laser market

The industrial-laser market is Coherent’s primary cyclical adjacency. The franchise originates with the legacy Coherent Inc. acquisition (closed July 1, 2022, $7.01B consideration) and includes industrial fiber lasers, ultrafast lasers, excimer lasers, life-sciences instrumentation, and laser-based materials-processing systems. Under the FY2026 reporting structure (Datacenter & Communications + Industrial), the entire industrial-laser franchise sits inside the Industrial segment along with materials/SiC.

Industrial-laser demand is structurally cyclical — driven by global manufacturing capex, particularly in China (machine-tool builders), Germany (machine-tool exports), Japan (similar), and the US (additive-manufacturing-led).

Market sizing

YearIndustrial fiber laser TAM ($B) ⚠Industrial laser system TAM ($B) ⚠Combined ($B)
2023~$2.5~$11–12~$13–14
2024~$2.4~$11~$13
2025~$2.5~$11–12~$13–14
2026 (forecast)~$2.6~$12~$14–15
2028 (forecast)~$3.0~$13–14~$16–17

⚠ Aggregator-house estimates. The growth is slow and cyclical — roughly 3–5% CAGR over multi-year horizons, with significant year-over-year volatility tied to manufacturing capex cycles. The fiber-laser source-component layer (where IPG Photonics and Coherent compete head-to-head) is roughly 20% of the total system TAM; the rest is the system-integration value (machine-tool builders’ add).

Cutting / welding / additive cyclicality

The three primary application verticals each have different cyclical characteristics:

ApplicationDemand driversCyclical character
Cutting (laser cutting machines for sheet metal)Industrial capex, automotive, fabricated-metalsMost cyclical — GDP-leveraged
Welding (e-mobility battery welding, automotive body)EV adoption, automotive capexLess cyclical than cutting; EV-cycle-tied
Additive manufacturing (3D metal printing)Aerospace, medical, space-techLong-cycle; less correlated with broader industrial
Marking/engravingConsumer electronics, packagingModerately cyclical
Microelectronics processingSemiconductor capexTied to WFE cycle (volatile)
Life sciences (genomics, bio-imaging)Healthcare capex, research budgetsStable, slow growth
Display / OLED processingConsumer-electronics OEM cyclesModerately cyclical

Coherent’s industrial-laser portfolio spans all of these (the breadth is a legacy of the Coherent Inc. acquisition). The most cyclical-exposed pieces are cutting and microelectronics; the most stable are life sciences and additive.

Coherent’s revenue contribution

Under the legacy three-segment structure (Networking / Materials / Lasers), Coherent’s Lasers segment posted $1.44B in FY2025 revenue (+2.8% YoY off a soft FY2024 base of $1.40B). Under the FY2026 two-segment structure, the Lasers segment merges with Materials into the Industrial segment, which posted:

  • Q1 FY2026 industrial revenue: ~$483M (calculated from $1.58B total – ~$1.10B datacenter/comm)
  • Q2 FY2026 industrial revenue: $477.6M (–9.9% YoY)

The FY2026 first-half industrial-segment trajectory is weak — flat-to-down YoY. This is consistent with the broader industrial-capex weakness in CY2025 H2 (Chinese export demand softness, European manufacturing stagnation, US machine-tool order softness). It’s also why management’s revenue-growth narrative is dominated by Datacenter & Communications: Industrial provides drag, not growth.

IPG Photonics comp

IPG Photonics (NASDAQ: IPGP) is the closest pure-play comp:

MetricCoherent Industrial segmentIPG Photonics
FY2025 revenue (calendar year)~$1.93B (FY2025 Lasers $1.44B + Materials $954M minus SiC = est.)~$1.0B (CY2025)
Geographic mixUS-led + globalChina-heavy (was; reducing)
Product scopeFiber lasers, ultrafast, excimer, materials, SiCFiber lasers (pure-play)
Margin profile~Mid-30s gross margin Industrial blend~30–35% gross margin
Cyclical exposureHigh (China capex sensitive)Very high (fiber-laser-cycle pure)
DiversificationBroad — life sciences, additive, materialsNarrow — fiber lasers

Coherent’s industrial-laser revenue is roughly 2× IPG Photonics’ total revenue, but Coherent’s franchise is more diversified (less China-exposed; broader product scope). When IPG Photonics is troughed, Coherent troughs less acutely; when IPG Photonics inflects, Coherent inflects less sharply too.

Trumpf comp (private)

Trumpf is the German private machine-tool builder + fiber-laser source vendor; it’s a vertical comp (builds laser systems and source lasers) rather than a pure-component comp. Trumpf has been gaining share in industrial fiber lasers globally and is a significant competitor to Coherent in cutting/welding systems and to IPG in fiber-laser sources.

What changes the industrial-laser thesis

  1. Industrial-capex inflection (positive or negative) — global manufacturing PMI is the leading indicator.
  2. EV adoption acceleration — would lift battery-welding laser demand and offset cutting-segment weakness.
  3. Additive-manufacturing breakthrough — large industrial customers committing to AM at scale would lift Coherent’s AM-laser franchise.
  4. Chinese trade restrictions — could reduce Chinese-customer-bound revenue (IPG more affected than Coherent).
  5. Life-sciences capex acceleration — academic-funded biomedical research has been a steady but small driver.

Confirmation paths and counter-signals

Industrial improving:

  • Coherent Industrial segment QoQ revenue inflection from negative to positive
  • IPG Photonics quarterly results showing stabilization
  • Global manufacturing PMI > 50 across multiple geographies
  • Coherent management commentary lifting Industrial outlook on subsequent earnings calls

Industrial deteriorating:

  • Continued YoY declines in Industrial segment (currently –9.9% YoY in Q2 FY2026)
  • Manufacturing PMI falling further below 50
  • Asian export-economy weakness extending into 2027
