AMS Technologies provides a broad range of pulsed and CW fiber laser systems with peak pulse powers up to 50 kW and wavelengths from 355 nm (UV) to 1550 nm (IR).
Pulsed Fiber Lasers
Our series of high-power pulsed infrared (IR) fiber sources consists of compact turnkey systems or OEM modules that are based on a highly reliable Master Oscillator / Power-Amplifier (MOPA) design to deliver multi-kilowatt level peak powers with average output powers of up to 1 W.
Operating in the nanosecond pulse duration regime, our high-energy pulsed infrared lasers have been designed for easy OEM integration and enable market-leading repetition rates whilst maintaining peak power. The nanosecond pulsed IR Raman source lasers are widely used in distributed temperature sensing (DTS) systems, laser ranging and fiber optic sensing systems. Compact master oscillator - power amplifier (MOPA) sources deliver 50 ns pulse width at wavelengths around 1.5 µm and can be directly modulated within certain limits of repetition rate and pulse power. High power density and an excellent beam parameter product after decoupling into free space make these light sources a preferred choice for many test and measurement applications.
Our ultrashort pulse fiber seeders for laser amplifiers providing pulse widths of 1 to 10 ps are free of consumable components like SESAM, which makes them exceptionally long-lasting. High-energy, air-cooled femtosecond lasers are available, delivering 450 fs pulses with energies beyond 100 µJ and repetition rates up to 1 MHz for microprocessing and a variety of ultrafast applications, or even shorter (typ. 60 fs) pulses with repetition rates up to 40 MHz for biophotonics, designed with multiphoton microscopy and other nonlinear optics applications in mind.
CW Fiber Lasers
A uniquely designed fiber filter ensures single frequency operation of the ultra-narrow linewidth CW IR fiber laser. This laser delivers output power of up to 50 mW and offers excellent performance featuring kHz-level linewidth, low frequency noise and intensity noise and a SMSR of more than 50 dB.
For OEM applications demanding higher output power, we carry a series of OEM CW IR fiber laser modules that are ready for system integration and provide output powers in the range from 500 W to 2 kW with both single mode and multi mode variants available. If you need even higher CW output power, take a look at our high-power CW IR fiber lasers that provide exceptional levels of power and control while cutting, welding and drilling with laser power of up to 10 kW for the water-cooled models.
Complementing AMS Technologies’ fiber lasers, our wide range of laser technologies encompasses DPSS lasers, diode lasers and gas lasers, as well as OPOs and tunable lasers or other lasers and light sources – and also includes an exceptionally broad portfolio of laser diodes, modules and systems for a wide variety of wavelengths and optical output powers.
For reliably cooling laser systems and laser components, we carry a very wide thermal management portfolio, ranging from components like thermoelectric, Peltier modules (TECs), heat sinks and fans to TEC- or compressor-based plate to air thermal management assemblies like our mini direct cooling thermoelectric kit, to liquid to air thermal management assemblies like recirculating chillers.
Laser safety products available from AMS Technologies include protective eyewear as well as laser safety windows, curtains and cabins.
Our large portfolio of precision optics, manufactured of various optical materials and coated to very specific and demanding tolerances, includes disk-shaped optical beamsplitters, optical scanners and deflectors, optical mirrors, windows, filters, lenses, prisms, polarization optics or etalons.
Additionally, we offer a broad range of complementary products such as optical mounts, rotary and translation stages, optical tables, breadboards and platforms as well as a variety of optical test and measurement equipment.
As a special form of solid-state laser, the doped core of an optical fiber represents the active laser medium in a fiber laser. Rare earths such as erbium, ytterbium, neodymium and others are used as doping materials. The fiber laser’s resonator is formed either by mirrored fiber end faces or a fiber Bragg grating inscribed in the active fiber itself or an undoped fiber spliced to it. Due to the resonator’s long length, the laser radiation experiences a very high amplification.
Fiber lasers are usually optically pumped by laser diodes whose radiation is usually coupled into the fiber cladding parallel to the fiber core. Double clad fibers allow higher powers. Fiber lasers can achieve more than 30% electrical-optical efficiency and feature a high beam quality.
Since the surface of the resonator is very large in relation to its volume and the fiber guides the laser light with very low losses, there are hardly any severe thermo-optical issues even if the medium is heated significantly. This enables high-power fiber lasers (most of them consisting of a fiber or diode seed laser and a downstream fiber amplifier) with output powers of several 100 W up to several kW. Today, high-power fiber lasers are widely used in material processing, for example for laser cutting and laser welding of metal and other materials.
Fiber lasers with doped optical fibers as the laser medium are to be distinguished from fiber-coupled lasers, where a fiber coupled to the output of the laser merely serves to guide the light generated by the actual laser (e.g. a diode or gas laser).
