VLM series

Visible CW single-mode laser sources
The VLM range comprises high-efficiency, volume-manufactured CW single-mode fibre lasers that emit linearly polarised light across the visible band (355–775 nm). Using advanced nonlinear frequency-conversion, they suit demanding use-cases in holography, scientific instrumentation, medical technology, laser projection and precision illumination.

Key features and advantages

Coverage across the visible spectrum (355–775 nm) with 0.1 nm selection steps, including violet-to-red outputs (357–660 nm) realised via harmonic generation.
Diffraction-limited beam quality with low spectral linewidth (<0.1 nm), with single-frequency variants available (VLM-SF).
Based on stimulated Raman scattering and other nonlinear conversion methods for efficient visible-light generation.
Well suited for pumping dye and Ti:Sa lasers, as well as holography, medical devices, research setups, projection systems and precision lighting.
No liquid chiller required — efficient thermal management simplifies integration and reduces system complexity.
Reliable operation across a broad ambient range where many alternatives would need additional thermal stabilisation.
Outperforms comparable offerings on functionality, output power, efficiency and flexibility — underpinned by robust, scalable manufacturing.
