or Cr<SUP><FONT SIZE=1>+4</FONT></SUP>:YAG - is a material that can be
used as an active media for CW, pulsed or self mode-locked tunable NIR
solid-state lasers with tunability range 1340 - 1580 nm as well as a media
for Q-switching in lasers with operating wavelength at 950 - 1100 nm.
It is particularly useful in practical applications because of convenient
absorption band of Cr<SUP><FONT SIZE=1>+4</FONT></SUP>around 1 mm which
gives possibilities to pump it by regular Nd:YAG lasers. A saturation
of absorption in the band at 1060 nm is useful for application in small
sized Nd:YAG oscillators with flash lamp or laser diode pumping instead
of based on dye or LiF:F-center passive Q-switches. Using the Cr<SUP><FONT SIZE=1>+4</FONT></SUP>:YAG
crystal the self mode-locking (KML) regime is achievable. It gives an
opportunity to build the laser source with pulse duration shorter then
100 fs at 1450 - 1580 nm.<BR>
Finally, its high thermal and radiation stability as well as excellent
optical and mechanical properties will give you an opportunity to design
reliable devices based on the crystal.

<STRONG>New availabilities for frequency conversion</STRONG>
</CENTER>
<br>
The Solid state Raman shifter RS-14 is an easy in operation device for
expansion of the tuning range of a Ti:Sapphire laser. In the Shifter are
used innovative technology Ba(NO<SUB><FONT SIZE=1>3</FONT></SUB>)<SUB><FONT SIZE=1>2</FONT></SUB>
crystals. The crystal unique properties, such as: optical homogeneity,
1047 cm<sup><FONT SIZE=1>-1</FONT></sup> shift, wide transparency range
allows utilization of these crystals for frequency conversion (practically)
in any (360 to 1500 nm) spectrum regions.<BR>
Unlike gaseous Raman shifters, there is no high pressure, complete safety
of operation, low input threshold powers - all this provides you with
additional ease of the usage.<BR>
The RS-14 provides highly efficient conversion of tunable radiation from
a Ti:Sapphire laser to tunable radiation of stimulated Raman scattering
at 1st, 2nd and 3rd Stokes components. The optimum conversion in the RS-14
is achieved at pump with a Ti:Sapphire laser operating in the wavelength
range from 815 to 900 nm. It allows to generate the tunable narrow-linewidth
radiation from 690 to 1245 nm at the output.<BR>
Used for radiation conversion Ba(NO<SUB><FONT SIZE=1>3</FONT></SUB>)<SUB><FONT SIZE=1>2</FONT></SUB>
crystal is located in the optimized cavity. Such an arrangement ensures
high efficiencies of the laser output conversion to the 1st or 2nd stokes
(30% or higher) along with a comparatively low output beam divergence
(1.5 mrad), enabling thus further non-linear conversion of radiation.
The diagram below illustrates the principle of the RS-14 operation.

<P>The Ti:Sapphire pump wavelength range is divided into two Subranges.
Subrange I refers to the operational wavelength range 815-960 nm, while
Subrange II corresponds to the operational wavelength range 850-900
nm of Ti:Sapphire. By choosing Type I or Type II tunability range and
using one from the available 6 pairs of cavity mirrors, tunable radiation
with the parameters as follows can be established at the RS-14 output:<BR>

In the RS-14 are used 6 pairs of specially designed changeable cavity
mirrors. By changing one mirror pair for another, highly-efficient generation
of tunable radiation of the 1st, 2nd and 3rd Stokes components individually
or together can be established at the RS-14 output. Low alignment requirements
of the cavity mirrors together with ease of their replacement simplify
the laser alignment procedure for operation in the wavelength range desired.
Telescopic / focusing system that comes together with the converter, allows
the RS-l4 to be adapted to any pump laser.
