The PL series of continuous wave (CW), grating tuned, infrared gas lasers, sets the standards for high power, stable sources for a wide variety of applications:
The PL-series of lasers include grating tuned CO2 lasers with a step tuneable wavelength from 9.1 μm – 10.9 μm with single line powers from a few Watts (Model PL2), to 50 W (Model PL5) and even to 180 W (Model PL6), each characterised by excellent amplitude and frequency stability for the most technically challenging tasks.
The PL2 laser lends itself to flexible tailoring to scientific applications. For example, if used with our 184T pump station, the laser head can be filled with the desired isotopic gas mix which gives the user access to a range of alternative wavelengths.
The higher power PL-series lasers can be used to optically pump polar gases (for example methanol, formic acid, etc) to create Far-Infrared (FIR) laser emission. The FIR/TeraHertz region (40 μm – 1.2 mm, or 7.5 THz – 0.25THz) can be used for temperature measurement of fusion reactor plasma. There are also many applications in homeland security and scanning, scattering density measurements, radar modelling, etc.

Tuning mechanism: Piezo-ceramic length tuner and diffraction grating wavelength selection
For applications demanding excellent medium and long tern stability, an active stabiliser may be required. This will compensate for laser output fluctuations caused by changes in ambient conditions and lock the variation in laser frequency or power to a value close to the passive jitter. Edinburgh Instruments has designed a family of active stabilisation techniques appropriate to the type of laser and operating conditions. Stabilisation of laser output is possible for up to 60 minutes.
All flowing gas laser systems are supplied with the necessary valves, gauges and vacuum couplings for simple connection to the system vacuum pump. A range of turbo molecular and dry pumps are available as upgrades. Please contact us for more information.
These are designed to allow mixing and metering of up to 3 component gases from independent gas cylinders. Comprising of 3 inlet ports with individual flow meters or needle valves for gas mixing or gas flow operation.
