Integrator Laser System
The Pryor InLaser is our new MOPA fibre laser built for system integrators and OEM manufacturers. The updated system now uses the latest MOPA (Master Oscillator Power Amplifier) source technology, a significant step forward that delivers greater control, superior marking on demanding materials including anodised aluminium and engineering plastics, and consistently better contrast across the full power range.
The system is supplied as a Class IV laser system and includes a new marking head paired with a redesigned rack-mount controller. The new controller is slimmer and lighter than its predecessor, with a cleaner profile and more flexibility in how it can be fixed and located within a cabinet or rack.
The scan head has been redesigned too. It’s noticeably smaller and lighter than the previous version. This means it easier to mount in confined spaces, position on a robot arm, or integrate into a multi-axis system without adding unnecessary bulk.
For integrators, the most important thing about any laser is how it communicates to the rest of the production line. The InLaser has been designed from scratch with exactly that in mind. A comprehensive set of standard and optional interfaces cover the full range of possible integration scenarios. From simple PLC start/stop inputs to EtherNet/IP, PROFINET, OPC-UA, and TCP/IP socket connections. And whether you’re working with Siemens, Allen-Bradley, or a bespoke software platform, there’s a communication option for you.
As with all lasers, the marking process is non-contact, which removes the need for complex fixturing. It can mark static parts or track components in motion, making it a strong fit for high-speed lines, robot cells, conveyor systems, and rotary tables. It handles metals, plastics, and coated materials with clean and consistent results.

- What is a MOPA laser source?
Features
Integrators and OEM manufacturers need a laser that fits neatly into a wider architecture, communicates reliably with everything around it, and simply and easy to use. This updated version of our popular integrator laser is a meaningful step forward in every area that matters to our customer. Designed and built to be the easiest Integrator laser to work with, whilst maintaining the Pryor quality and performance.
MOPA Laser Source
The switch from conventional pulsed fibre to MOPA technology is the most significant change in this generation of the InLaser. The key advantage is control. Where a standard pulsed fibre laser fires pulses at a fixed duration, a MOPA source allows pulse width to be set independently of the repetition rate. That gives far greater flexibility in how the mark is produced, meaning cleaner results on heat-sensitive materials, better contrast on anodised aluminium, sharper marks on plastics, and more consistent performance across a wider frequency range. For integrators building systems that handle a variety of components or materials, that additional control can open up lots of new opportunities and potential products for laser marking.
Redesigned Controller
The new controller has been redesigned in terms of aesthetics and practicality. It’s lighter and slimmer than the previous version, with a cleaner look that sits more comfortably in a modern automation cabinet or next to a production line. More importantly, there are more options for how it can be fixed and located, useful when the system needs to integrate within an existing location or where weight is a critical factor.
New Compact Scan Head
The laser scan head is also new. It’s smaller and lighter than the previous version, ideal for when mounting in a restricted space, integrating onto a robot arm, or designing a multi-axis cell with tight constraints. Less bulk makes positioning easier and allows for integration possibilities that would have required more compromise with the previous design.
Communication and I/O
The system supports two operating modes: 1) Embedded/standalone and 2) PC-controlled, and the communication options available reflect the full range of scenarios integrators might encounter during a project.
In standalone mode, standard interfaces include:
- RS-232,
- 24V digital I/O (8 inputs, 6 outputs, expandable to 24 inputs and 18 outputs across three banks),
- a dedicated start/stop input,
- USB for scanner or reader connectivity.
For fieldbus environments, optional modules add EtherNet/IP for Rockwell/Allen-Bradley PLC systems or PROFINET for Siemens environments. Ethernet TCP/IP socket connectivity is also available for custom software or MES integration.
In PC controlled mode using Pryor’s traceability software, the system gains OPC-UA connectivity, a vendor-neutral, multi-brand protocol with bidirectional data exchange. That means the wider automation system can send data to the laser and receive confirmation, or variable data, back in real time. This provides live traceability verification without additional software layers.
For safety, it has:
- dual-channel door interlocks
- multiple E-Stop inputs
- a Busy/Ready relay output,
- E-Stop monitoring contacts for integration into the safety circuit of a wider system.

Communication Options
Communication & I/O Options
The laser controller supports two fundamental operating modes. The interfaces available depend on which mode suits your application.
| Mode 1 — Embedded / Standalone
The laser runs autonomously using its onboard controller and layouts. A touchscreen is recommended. Best suited to applications with a defined, repeatable set of marking layouts. |
Mode 2 — PC-Controlled
The laser is driven by MarkMaster or Traceable-IT software running on a connected PC via USB. The better choice where significant part variety exists and frequent layout creation or modification is required. |

What is a MOPA laser source?
MOPA laser marking is fast, precise, and non-contact, which makes it an ideal technology to build into high-speed production lines. Because there’s no physical contact with the part, there’s no need for additional clamping or fixturing, keeping the integration design clean and the cycle time short.
The variable pulse control that defines MOPA technology means the same system can handle a wide range of marking styles and materials without switching configurations. High-contrast surface marks, deep engraving, annealing on stainless steel, or marking on plastics. The InLaser handles them all within its standard operational envelope.
