1. STM10 & STM20 High Energy Pulsed Fiber Laser

STM10 and STM20 series of laser products are rugged compact pulsed fiber lasers intended for integration into industrial equipment. These lasers offer 10W or 20W average power which is delivered via a flexible output fiber and collimating optics. These high peak power pulses are suitable for applications such as marking, engraving, micromachining, and surface treatments.

Pulse repetition rate and output power can be controlled either by 8-bits TTL signal or USB, providing the user both fast communication and user-friendly interfaces at the same time.

Due to excellent pump to signal efficiency in the optical fiber, these powerful air-cooled laser systems are maintenance free with significantly low operational costs.

The standard systems come with an optical output isolator. Additional beam expander, focusing lens, and red aiming beam are optional.

Options:

l     Red aiming beam

l     Beam expander and focusing optics

l     24VDC Power Supply

l     Delivery fiber cable lengths on request

l     Shorter pulse durations on request

2. STM20HF High Frequency Pulsed Fiber Laser

Built on same robust architecture than STM10/M20, this laser takes advantage of our specific optical design to reach very high performances at high repetition rate using a fully compatible interface and package.

Because of its high peak power available at high repetition rate and short pulse duration (20ns), STM20HF is ideally suitable for high speed paint / anodize / coatings removal, selective ablation and metal oxidation.

To achieve fine marking even on small components such as semi-conductor, STM20HF is doted with an excellent beam quality; spot diameter as small as 30µm are easily achievable with 160mm focal length.

This new laser is fully compatible and complementary of STM10/STM20 and designed to cover an extended range of applications keeping same high reliability and ease-of-use.

Highlights

- Average Power: 20W

- High Beam Quality

- High Repetition Rate

- Ease of use

- Maintenance-free

Options and accessories

- Focusing and Collimating Optics
- Red Aiming Beam
- Multiple Output Fiber Lengths

3. STM20EG Fiber Laser

The STM20EG is a new product based on our STM20 platform. This rugged compact pulsed fiber laser is intended for integration into industrial equipment.

This laser delivers 20W average power via a long flexible fiber delivery and collimating optics.

Its high peak power pulses combined with enhanced beam quality are ideal for applications such as deep engraving, and hole drilling even on highly reflective material such as gold and copper.

With its enhanced optical design and isolation, the STM20EG is insensitive to back reflection. The laser is delivered with a full warranty including marking on copper or highly reflective materials. As part of STM series, STM20EG might be driven either by TTL signal (8 bit TTL for power setting, synchronization signal for repetition rate and activation signal to switch on/off the laser) or by its user-friendly USB software.

Highlights

- High peak power

- Enhanced beam quality

- Warranty on highly reflective materials

Options and accessories

- 12 mm beam expander

- Red aiming beam

4. STM30EG Fiber Laser

The ideal laser for high speed engraving on all metals

The STM30EG is a rugged and compact pulsed fiber laser intended for integration into industrial equipment.

This laser delivers 30W average power via a long flexible fiber delivery and collimating optics. Its high peak power pulses combined with high average power are ideal for fast deep engraving and holes drilling applications even on high reflective materials such as gold and copper. Short pulse duration and high beam quality further improve texturing and isolation for photovoltaic applications without degrading heat affected zone (HAZ).

As part of the STM series, STM30EG might be driven either by TTL signal (8 bit TTL for power setting, synchronization signal for repetition rate and activation signal to switch on/off the laser) or by its user-friendly USB software.

Options and accessories

- 9 mm beam expander

- Red aiming beam
