01 · Lab

An optical bench.
This is where
we work.

A vibration-isolated steel table covered in our own fiber lasers and the optics that go around them. Most days, this is where you'll find us.

02 · Source

A fiber laser
we designed.

Doped fiber, diode pumps, Bragg gratings, mode-locking elements. We keep finding ways to make these better.

03 · Steering

Aligned by hand.

Two mirrors, four micrometer screws. A careful, iterative process — turn a knob, check the spot, turn again.

04 · Polarization

Polarization,
controlled.

Half-wave plates, polarizing splitters, polarization-maintaining fiber. Managing the state of light is a big part of how our systems work.

05 · Focus

To a few microns.

An aspheric lens collapses the beam to its diffraction limit. With short enough pulses, you can cut metal cleanly without heating up the material around it.

06 · Measurement

Everything
measured.

Optical spectrum, RF beat note, polarization extinction, beam quality. Nothing leaves the lab until we know how it actually behaves.

01 · FS

Femtosecond fiber lasers

ultrafast pulsed sources for spectroscopy, microscopy, and time-resolved experiments.

02 · μP

Micro & nano processing

cold ablation of metals, polymers, and ceramics — no heat-affected zone.

03 · CW

Continuous-wave fiber lasers

stable single-frequency sources for research and material processing.

04 · NL

Narrow-linewidth 1550 nm

eye-safe coherent sources for lidar, sensing, and coherent detection.

05 · RX

One-of-a-kind systems

sources built from scratch when no off-the-shelf laser fits the experiment.

06 · PE

Polarization & fiber optics

specialty fiber-optic assemblies and polarization-management components.
