Laser Solutions for Scientific Applications​

Lasers for advanced and scientific applications often require demanding specifications such as very precise wavelengths, narrow linewidths, or exacting pulse parameters. As the world leading producer of fiber lasers, IPG provides a wide range of standard and custom laser solutions for scientific users. IPG lasers are used in a variety of advanced applications including spectroscopy and bioimaging, optical trapping, LIDAR, metrology, atomic physics, and many more.

Excellent beam quality, stability, and precise control of laser parameters ensure repeatable results in long term experiments or measurements where any fluctuation in laser performance could impact results. A compact design and flexible fiber beam delivery make IPG lasers easy to integrate into experimental setups, simplifying integration and adjustment in applications with limited space or changing setups.

Wavelength Tuning

Laser wavelength is a critical consideration for high-precision material processing, spectroscopy, microscopy, metrology, sensing, and other advanced applications. Laser wavelength determines the rate of energy absorption by materials and affects a variety of properties such as scattering, reflection, and minimum achievable focal spot size. IPG offers diode, fiber, and solid state fiber-hybrid lasers with wavelengths from 257 nm to 5000 nm to address applications from deep-UV to mid-IR. For applications with demand wavelength requirements, IPG offers tunable wavelength lasers in the mid-infrared range as well as lasers with fixed custom wavelengths.

Linewidth & Frequency Control


Used to describe the spectral width of a laser beam, laser linewidth refers to the range of wavelengths emitted by a laser. Linewidth is measured as the full width at half-maximum (FWHM) of the laser’s optical spectrum. The term “narrow linewidth laser” typically refers to lasers with linewidths smaller than 1 nm, in 0.1 to 0.01 nm range.

Lasers referred to as “single-frequency lasers” typically have bandwidth expressed as frequency, from MHz to kHz, or sometimes in Hz range. IPG offers a variety of single-frequency and narrow linewidth lasers with high spectral purity and low intensity and phase noise — these lasers operate in a single resonator mode, which results in an extremely narrow bandwidth and low phase noise. This laser technology is employed for precision applications, where stable and narrow frequency, as well as minimal noise, is crucial, such as telecommunications, LIDAR, and scientific instruments.

Random & Linear Polarization

Although the polarization of laser light is not critical for most materials processing applications, polarization is an important property for certain applications. Polarization is essential for understanding how laser light is focused, wavelength interactions with the target, and controlling the absorption and reflection of the beam. IPG lasers are randomly polarized by default but are also offered linearly polarized with a variety of polarization extinction ratios. Linearly polarized IPG fiber lasers emit light with a single preferred direction of oscillation. This stable, linearly polarized output makes these lasers valuable for applications where controlled polarization is essential, such as in telecommunications, materials processing, and scientific research.

Laser Amplification & Power Beaming

Compatible with user-supplied or IPG seed lasers, IPG Continuous Wave (CW) fiber amplifiers provide kilowatt class output power with a variety of polarization and linewidth options. CW amplifiers are used in a wide range of applications including optical metrology, atom trapping, high resolution spectroscopy, spectral beam comping, and power beaming.

High-energy power-beam lasers offer many kilowatts of continuous power in low order, low divergence beams to deliver energy over long distances and eliminate the need for wires or fuel sources. Fiber lasers for power beaming experience negligible thermal lensing, enabling dynamic power tuning from 10 to 100% with no change in beam divergence or beam profile. IPG offers a variety of fiber lasers for power beaming applications, including high-power single mode lasers and specialized lasers with multiple spatial modes combined into a uniform round beam on long distance targets.

Ultrafast Pulse Shaping

Ultrafast pulse shaping allows for the creation of a desired temporal pulse shape, from the shortest near-transform-limited pulse to a variety of waveforms. The most common application for ultrafast pulse shaping is dispersion pre-compensation to achieve a near-Fourier-transform-limited pulse duration at a target location rather than at a laser output. The shortest pulse duration results in the highest laser peak power at the target, maximizing the efficiency of non-linear processes in various applications such as multi-photon microscopy, non-linear spectroscopy, high harmonic generation, and filamentation. For ultrafast applications that demand specific tailoring of pulse shapes or pulse sequence times, IPG offers integrated femtosecond lasers with programmable pulse shapers and standalone femtosecond pulse shapers.
