What Vexlum does

Vexlum Oy is a Finnish deep-tech company headquartered in Tampere, founded in 2017 as a spin-off from the Optoelectronics Research Centre (ORC) at Tampere University. The company designs and manufactures high-power, narrow-linewidth single-frequency semiconductor laser systems based on proprietary Vertical-External-Cavity Surface-Emitting Laser (VECSEL) technology. Operations are vertically integrated, encompassing in-house molecular beam epitaxy (MBE) of III-V semiconductor gain structures, cleanroom semiconductor processing, optical coating, and full laser system assembly. This integration enables broad wavelength coverage from 350 nm to 2150 nm, multi-watt output, sub-100 Hz linewidth, and tunable operation in a compact footprint.

Vexlum markets two product platforms: VALO, optimized for atomic, molecular, and optical physics research (up to 10 W, sub-100 Hz linewidth, 350–2150 nm); and VXL, a next-generation compact (~2-liter) modular VECSEL platform launched in January 2026 for enterprise and industrial deployment requiring 24/7 operation. Sales are conducted through direct enterprise engagement, a US subsidiary (Vexlum US Inc., Broomfield, Colorado, established 2023), and an exclusive French distributor (Opton Laser International). Target segments are quantum computing (trapped-ion and neutral-atom systems), optical atomic clocks, semiconductor manufacturing and metrology, space/aerospace (ESA adaptive optics), and scientific research.

Revenue is generated primarily through one-time hardware sales of configured laser systems under a quote-based pricing model, supplemented by technical support and service. The company has publicly targeted EUR 100 million in annual revenue by 2030. Capitalization is anchored by a EUR 10 million financing closed in February 2026—the largest seed round for a Nordic photonics company—comprising EUR 6 million in equity (Kvanted-led, with Tesi and EIC Fund), a EUR 2.4 million EIC Accelerator grant, and a EUR 1.6 million Nordea loan, intended to scale Tampere-based semiconductor fabrication and move from boutique to industrial production.

Core offering

Vexlum designs, manufactures, and sells high-power, low-noise single-frequency semiconductor laser systems based on proprietary VECSEL (Vertical-External-Cavity Surface-Emitting Laser) technology. The company offers two main platforms — VALO for research applications and VXL for enterprise/industrial deployment — covering wavelengths from 350 nm to 2150 nm with power outputs up to 10 W and sub-100 Hz linewidths. Production is vertically integrated from III-V molecular beam epitaxy (MBE) through cleanroom processing to full laser system assembly.

Product overview

Vexlum is a Finnish deep-tech company specializing in high-power semiconductor laser systems based on proprietary Vertical-External-Cavity Surface-Emitting Laser (VECSEL) technology. The company offers two distinct product lines: the VALO platform for research applications and the VXL platform for enterprise/industrial deployment. The VALO series provides high-power low-noise single-frequency lasers with broad wavelength coverage (350 nm to 2150 nm) designed for atomic, molecular, and optical physics research. The VXL series delivers the same performance capabilities in a dramatically smaller form factor (more than 20-fold volume reduction), optimized for system integration and 24/7 industrial operation. Both platforms utilize VECSEL technology combining semiconductor gain structures with external cavity architecture, enabling wavelength versatility, multi-watt power, tunable narrow-linewidth operation, and high beam quality. Applications span quantum computing (trapped-ion and neutral-atom qubits), optical atomic clocks, semiconductor metrology, space communications, and scientific research.
