Nanosecond Fiber Lasers

IPG’s nanosecond fiber lasers are ideal for industrial

applications from laser ablation, marking, trimming,

scribing, micro-machining, diamond and silicon

cutting, to high speed hole drilling. They feature

low divergence and can provide the fluence

required for high speed marking of both

plastics and metals, including highly

reflective materials. High power

lasers are optimized for surface

treatment applications.

From UV to Mid-IR, from

1 W to 5 kW, the versatility

of IPG's pulsed fiber

lasers is unparalleled.

Nanosecond Pulsed Fiber Lasers

A nanosecond is one billionth of a second. In that one billionth of a second IPG’s pulsed nanosecond fiber lasers can interact with a range of materials to mark, ablate, clean, scribe, cut, engrave and drill.

IPG produces the broadest range of pulsed nanosecond lasers in the world, with a wide range of operating parameters to perfectly suit all demanding application requirements.  


With average powers from 10 W  to 5 kW, pulse energies from 1 mJ to 100 mJ, peak powers from 10 kW to 1 MW, low order beam modes, adjustable or fixed pulse waveforms, wide range of pulse repetition rates, simple customer interfacing, compact size and unrivalled reliability, IPG is ready to help you find the perfect laser solution to meet your application requirements.


Nanosecond fiber lasers with good beam quality (low M2) are excellent for marking and microprocessing/ micromachining applications. The introduction several years ago by IPG Photonics of low average power nanosecond fiber lasers for general purpose marking has led to a sea-change in the laser industry with almost every supplier of laser marking systems switching over to this type of fiber laser. A range of lasers from 10


up to 500 W average power and with both fixed (from 1.5  ns to 500 ns) and variable programmable pulse durations are now available.

Higher power pulsed fiber lasers with higher M2 value are optimized for large surface area treatment applications.  The range of average powers is from 100 W to 5 kW, the pulse energy is up to 100 mJ, and the beam spot size is optimized for high throughput.


IPG Photonics offers pulsed lasers at various wavelengths from UV to Mid-IR, allowing users to address many different types of materials. Infrared pulsed fiber lasers are available at 1, 1.5 and 2 µm. Non-linear external conversion produces green and 355 nm nanosecond output. 

IPG Photonics also manufactures bulk pulsed  Mid-IR hybrid lasers lasers operating in nanosecond range that complement this line of pulsed fiber lasers:

Er:YAG lasers (1.65 mm)
Ho:YAG lasers (2.09 mm)
Cr:ZnSe/S lasers (1.8-3.5 mm)
Fe:ZnSe/S lasers (3.54-5.2 mm)

  • Ytterbium 1 micron nanosecond fiber lasers are available in many models spanning 1 to 500 ns range.
  • Erbium 1.5 micron pulsed lasers range from 1 to 100 ns.
  • 355 nm, green and 2 micron (thulium) pulsed lasers are offered at 1-1.5 ns.

Features of Nano Pulse Fiber Lasers

Peak Power Range for 10 kW to 1 MW Excellent Pointing Stability
Wide Selection of Fixed and Adjustable Pulse Waveforms High Wall-plug Efficiency
Wide Range of Repetition Rates Compact Rugged Packaging
Wide Variety of Beam Qualities Optimized for Application
Pulse Energy and Pulse Peak Power are Independent of Repetition Rate

IPG Q-switched fiber lasers have several distinct advantages over DPSS bulk lasers:

  • no thermal lensing
  • easy to change pulse temporal waveforms
  • excellent pointing stability
  • high energy efficiency
  • exceptionally long pump diode lifetime
  • rugged design
  • low cost

Bulk DPSS lasers are characterized by intrinsic thermal lensing in the crystal that requires their design to be optimized around a limited range of pulse repetition rates and pulses energies. Changing these parameters over a wider range is usually not possible, as this would lead to a laser misalignment. Adjustments of pulse repetition rate and pulse 


energy even over a narrow range affects beam mode quality parameters such as divergence, astigmatism and M2. On the contrary, the absence of thermal lensing in fiber lasers allows user to change pulse repetition rate and pulse duration in a very wide range without affecting beam mode parameters. This allows the user to freely choose optimal parameters for each and every application.

The absence of thermal lensing in fiber lasers also facilitates adjustments of pulse duration/ pulse waveforms. The ability to adjust pulse durations by selecting the appropriate pre-programmed pulse length / pulse frequency combination brings the ultimate flexibility in achieving optimal results in many applications.

Fiber lasers are by their very nature fiber delivered, this is not only more convenient than free space delivery, but also comes with exceptionally good pointing stability. While fiber-coupling bulk DPSS lasers is possible, it leads to significant losses in average power and power stability.
