Panasonic, LP-RV Series

In 1999, we introduced the FAYb laser marker LP-F series, the world's first laser markers equipped with a fiber oscillator. Since then, we have launched various product lineups as a leading manufacturer of fiber laser markers for approximately 20 years.
The fiber oscillation system is recognized as an ecological system because its consumption power is low and the laser diode service life is long compared with YAG or YVO4. However, there was a problem that it's difficult to generate short pulse laser.
Through adopting a new three-unit configuration, the LP-RV series with fiber oscillation system has realized a short pulse with the pulse duration of 1 ns.
This will contribute to providing overwhelming improvement on expressive power and application needs.

Pulse oscillation fiber laser marker (FAYb laser)
What is FAYb laser?

In a revolutionary method, the FAYb laser amplifies a weak laser beam from a master oscillator as it passes through a fiber treated with the element ytterbium to emit a strong laser beam.

Long life and high reliability

The LD contains reliable and durable InGaAs (gallium indium arsenide). Since the LD lights only during marking, the heat load remains minimal and the product provides a long life.

High efficiency and energy saving

Because laser amplification takes place inside the fiber containing ytterbium, high beam-to-beam conversion efficiency of approximately 50 % is achieved.

Compact head

The amplification section is contained inside the oscillator unlike solid lasers such as YVO4, so the head is compact and contributes to the reduction of equipment size.

Short Pulse Laser

Through adopting our new technology, the new series with fiber system has achieved to generate a short pulse with the pulse duration of 1 ns.
The expressive power has been overwhelmingly improved.

Small thermal effect

As the thermal effect caused by the short pulse laser on the workpiece is small, burning, discoloration, or deformation due to heat is minimized. Therefore, the short pulse laser can be used as an optimal laser marker for devices where the thermal effect need to be suppressed such as ICs or thin metals or for high contrast marking on resin surfaces.

High repetition pulse oscillation

As the LP-RV can generate a short pulse laser beam in high repetition pulse oscillation, even if the laser beam is scanned at a higher speed, marking or processing is possible without spaces between laser-irradiated dots as shown on the right figure. This contributes to shortening the laser marking or processing takt time and to improving the quality.

Marking extra small characters

As the short pulse laser can prevent heat from spreading when laser is irradiated on a workpiece, it allows marking characters in much finer line segment.
It is possible to mark characters as small as 0.15 mm × 0.15 mm 0.006 in × 0.006 in. Marked characters are highly visible, not illegible at all.

Easy to install

Three-unit configuration

The laser marker features a three-unit configuration that allows each one of the three individual units to be separately removed and replaced depending on the problem in case any problem occurs. It contributes to shortening the down time.
* Before removing the unit, please contact your sales representative.

Easy setting

Laser Marker NAVI smart

Using the software, characters, logo marks, and 2D code can be set and arranged on a PC or tablet. The screen layout can be customized to suit each work environment. The screen can be switched according to the purpose of use, such as for parameter setting or for workers.

【Smart condition setting function】
The one-touch function is packed with our extensive know-how　of laser marking parameters such as laser power, scan speed　and pulse oscillation frequency. The user can select a desired　marking result from 14 types of material and image.

Open network connection (optional)

If you connect EtherNet/IP or PROFINET to the laser marker using the laser marker communication unit^*, marking contents or laser parameters can be set via the open network.

Direct linkage with machine vision system

Automatic marking position correction and scan check

The LP-RV series can be connected directly to the PV230 series machine vision system.
This enables the execution of a series of operations, such as detection of the position of approximately placed workpiece, correction of the laser irradiation position, laser marking, and cross-checking of scanned information of marked QR code, etc., without using a PLC.

Direct linkage with machine vision system

Automatic marking position correction

The PV230 scans and detects the position of the workpiece placed in the equipment.

Laser marking

The angle is corrected based on the scanned position information before the LP-RV irradiates laser beam.

Cross-check of scanned code information

Whether the marked 2D code can be scanned properly is checked, and the scanned information is crosschecked with the marking data.

Rich marking expressions

LP-RV series short pulse laser not only allows color marking on resin materials, but also provides higher marking quality for various materials and faster marking speed. The following section shows parameters for marking condition as reference.

*	Each parameter value is given for reference. Marking state varies depending on the surface condition, etc. of the material used.
*	Note that corrections may have been applied to some of the laser settings given below with respect to marking conditions for surface preparation, characters, and 2D codes. For further details about the parameter values, please contact us.
