Thermal Management Is Critical to Laser Performance
Laser diodes and laser crystals are extremely temperature-sensitive. As temperature rises, wavelength drifts, output power drops and the laser loses stability — reducing cutting, welding or marking quality. That is why every high-power laser system needs precision cooling engineered for its exact thermal load and optical layout.
At BY Thermal we design and manufacture the cooling structures that keep laser systems stable: liquid cold plates for high heat flux, thermally managed housings for optical and electronic modules, and high-density skived heat sinks for air-cooled laser modules.
Liquid Cooling
Cold plates with fiber routing, embedded tubes and microchannels for high heat flux.
Housing Cooling
Optical and electronics housings engineered for heat paths and mounting.
Air Cooling
Skived and extrusion + CNC heat sinks for laser modules and drivers.
Custom Laser Cooling Products & Structures
These are the laser thermal structures we manufacture most — every one custom-machined and built to your drawings.
Fiber Routing Cold Plates
Liquid cold plates with fiber routing slots and water channel structures, custom-machined to keep optical fibers and high heat flux within a controlled temperature window.

Laser Optical Housing Cooling
Thermally managed housings for laser optics and resonant cavities — engineered heat paths, precision-machined mounting surfaces and stable temperature control for beam quality.

Laser Electronics Housing Cooling
Skived fin heat sinks for laser power supplies, IGBT and drive electronics — high-density fins and CNC-machined mounting that protect sensitive circuits from thermal overload.

Skived Heat Sink + CNC
One-piece skived fins with a CNC-machined base, top plate and mounting holes — high fin density for compact air-cooled laser modules, all produced in-house.

Extrusion + CNC Thermal Housing
Custom-machined from extrusion profiles based on customer drawings — not standard stock profiles. Custom lengths, drilled and tapped mounting features, machined steps and pockets for housings and enclosures.
