OPOs and Tunable Lasers

Product Portfolio
AMS Technologies carries a broad range of tunable laser sources, based on OPOs, tunable resonators or other technologies like Raman scattering and tunable filters.

OPOs (Optical Parametric Oscillators)

AMS Technologies’ subsidiary Elforlight provides a tunable OPO source that combines pump laser and OPO in a single, rugged housing and generates very short laser pulses in the mid-infrared (MID-IR) range from 1700 to 1750 nm – the applications for such wavelengths are mainly in the field of photoacoustic imaging, in addition to gas chromatography and other analysis tasks. Other wavelengths are available on request.

Our mid-IR, optical parametric oscillator (OPO) pulsed laser source combines a wide spectral tunability (7.5 µm to 13 µm or 3 µm to 5 µm), with a very narrow linewidth down to 100 MHz. With the optional additional optical parametric amplifier (OPA) stage, the source also features high peak power and pulse energy.

Tunable CW Lasers

Our miniaturized, swept tunable external cavity lasers are driven by a circuit designed for low noise and highly linear swept performance appropriate for a variety of fiber optic test, measurement and sensing applications. They provide high wavelength precision and resolution combined with a highly linear wavelength sweep.

A series of tunable lasers in an OEM module format is available, based on a volume-produced integrable tunable laser assembly (ITLA) for the telecom market. These full-band tunable laser solutions are controlled through a digital interface, providing a very narrow linewidth (~10 kHz), significantly reduced low-frequency AM and FM noise and different operating modes.

Our 200 kHz swept laser light source for OCT imaging allows for highest speed wavelength sweeping. Emitting wavelengths in the 1.3 μm band, the swept light source is ideally suited for OCT-based examination of the coronary arteries. The device accelerates image acquisition and as a result reduces diagnosis time.

Tunable Pulsed Lasers

AMS Technologies’ subsidiary Elforlight provides a diode-pumped solid-state (DPSS) laser that allows switching from pulse to pulse between four wavelengths in the visible range (532, 55, 579 and 606 nm) with a very high pulse repetition frequency of 2 kHz. It emits very short laser pulses (<5 ns) of high energy (up to 20 µJ).

Our wide range of laser technologies encompasses DPSS lasers, diode lasersfiber lasers and gas lasers, as well as OPOs and tunable lasers or other lasers and light sources – including also an exceptionally broad portfolio of laser diodes and modules for a wide variety of wavelengths and optical output powers.

Further available light sources comprise LEDsSLEDs and broadband, ASE and supercontinuum light sources. Other lasers and light sources provide additional solutions like Nd:YAG lasers, frequency mixers and doublers, frequency conversion units or a ready-to-use solution for sterilizing items using UVC light.

Ultra-compact and highly reliable laser diode drivers address the requirements for low, medium and high power laser diodes, bars, stacks and modules, providing constant current or constant power mode with industry-leading stability.

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.

Definition
OPOs or Optical Parametric Oscillators are based on non-linear crystals. Pumped by a laser, these crystals emit two different light beams of lower frequency, where the sum of these two frequencies corresponds to the frequency of the pump laser.

The two light waves emitted are referred to as "signal" and "idler", with "signal" denoting the light beam with the higher frequency. Within an OPO’s resonator, oscillation only occurs when the pump laser’s output power level exceeds a particular threshold.

There are two ways to change the wavelengths of the emitted light waves: Either the pump laser’s wavelength is changed or the properties of the non-linear optical crystal by changing its temperature or orientation.

Tunable lasers are laser sources whose output wavelengths can be changed in a targeted and controlled manner. All laser media accommodate small shifts in wavelength, but only a few types of lasers allow continuous tuning over a relevant wavelength range.

Tuning can be reached by altering the length of the laser cavity, the temperature of the laser medium or by using optical elements like Bragg mirrors or multiple-prism grating arrangements. Applications for tunable lasers are found in areas like spectroscopy, photochemistry or optical communications.
