A choice of FIR lasers from Edinburgh Instruments to meet
applications requiring coherent radiation
in the range of
40 microns to 1.22 mm (0.25 to 7.5 THz). Invar bar stabilised
295 FIR : single output, 150mW output (using a pump CO2
laser such as PL5), 500mW (using a pump source as PL6) at
118.8 and 184.3 microns, isotopic fills
395 FIR : Dual FIR output ; utilises single pump CO2
source (e.g. PL5, PL5-S, PL6)
FIRL 100 : Has both the pump CO2 source and FIR laser
housed in an integrated structure ; FIR output at 118.8
micron is guaranteed at 150mW. The lasers and coupling
optics are mounted within a 5 bar invar rod frame for
excellent thermal and
mechanical stability. The CO2 section
provides 80 lines between 9.1 and 10.9 microns and
features a flowing gas single discharge tube giving more
than 50w on the strongest lines. Mode performance is (M2
< 1.25) is assured by internal profiling of the tube and
the use of highest quality optics. The resonator design
is based on the proven PL5 laser
with diffraction grating, two ZnSe Brewster windows and
peizo ceramic mounted ZnSe output coupler.
The
FIRL 100 Far Infra Red laser gas a 1.5m long pyrex
waveguide of 36mm diameter. The pump beam is input via a
Brewster window and input coupling with central
aperture. FIR radiation is extracted via a unique,
customised dichroic output mirror with wideband
transmission. |
