Laser Industry Gas & Pressure Control

Precision Flow & Pressure Solutions for the Laser Industry (UK)

Laser cutting, welding, and marking rely on stable assist‑gas delivery, accurate resonator gas blends, and clean purge air. CO₂, N₂, He and O₂ flows must remain consistent to maintain beam quality and prevent contamination.

Pressure fluctuations or dosing errors can cause mode instability, poor edge quality, and downtime. Premier Control Technologies provides UK‑based support for Alicat, Fluid Metering, Fusion Flow, and Drastar — brands trusted by laser OEMs and end‑users worldwide.

Alicat — Fast, Flexible Gas Flow & Pressure Control

Benefits for laser applications

Ultra fast response (50–100ms) for assist gas pulsing and resonator gas modulation
Multi gas capability lets you switch between CO₂, N₂, He, O₂ without recalibration—ideal for R&D and multi mode lasers.
Vacuum ready MCV series with positive shut off prevents backstreaming and protects resonator integrity.
Integrated pressure controllers (PC/PCS) stabilize beamline or chamber pressure, reducing overshoot during valve changes.
Connectivity: Analog + Modbus/EtherCAT for easy integration with laser control systems.

The Result

Improved cut quality, reduced gas waste, and faster recipe changes for high precision laser processes.

Fluid Metering — Pulseless Liquid Dosing for Coatings & Coolants

Benefits for laser applications

Valveless ceramic piston pumps deliver drift free, pulseless flow for laser optics coatings, coolants, or specialty fluids.
Handles micro volumes to liters per minute with repeatability—critical for thin film coatings or additive dosing in laser optics manufacturing.
Simple maintenance and reversible flow reduce downtime in high purity environments.

The Result

Consistent coating thickness and reliable coolant dosing for laser optics and components.

Fusion Flow — Accurate Resonator Gas Mixing

Benefits for CO₂ lasers and R&D labs

NIST traceable calibration ensures precise CO₂/N₂/He blends for resonator stability.
Fast step changes (<50ms) support dynamic recipe control during laser tuning.
Compact, plug and play panels simplify installation and reduce commissioning time.
Optional humidification and data logging for process traceability.

The Result

Stable resonator performance, improved beam quality, and reduced gas costs.

Drastar — UHP Pressure Regulation for Clean Gas Supply

Benefits for laser systems

316L stainless steel, electropolished internals, metal face‑seal connections maintain purity for resonator gases.
Low droop performance keeps inlet pressure stable to Alicat MFCs, improving flow accuracy.
High flow regulators (DR70/DR90) handle assist gas headers for cutting/welding systems.
Automatic changeover systems ensure uninterrupted resonator gas supply during cylinder switchover.

The Result

Stable resonator performance, improved beam quality, and reduced gas costs.
