The diagramm illustrates the principles of work of CRS14: 

?

The CRS14 uses 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 3d Stokes components individually or together can be established at the CRS14 output. 

The Ti:Sapphire pump wavelength range is divided into two Subranges. 

Subrange I covers the operational wavelength range 815-850 nm, 

while Subrange II covers the operational wavelength range 850-900 nm of Ti:Sapphire laser.

By choosing between Subrange I or Subrange II and choosing one of the available 6 pairs of cavity mirrors, 

tunable radiation with the parameters as follows can be established at the CRS14 output:

For Ti:Sapphire output from 815 to 850 nm (Subrange I) CRS14 provides:

a set of mirrors for providing simultaneous generation of the 1st, 2nd and 3rd Stokes radiation componentsUpon request CRS14 can be completed with:

• a telescopic system to ensure optimum power densities in a Ba(NO₃)₂
• a second harmonic generator to extend the tunability range from 350 to 620 nm

CRS14 solid state Raman shifter for conversion of tunable Ti:Sapphire laser output, combined with a

Ti:Sapphire pump laser, allows generation of a tunable narrow-linewidth  output radiation in the 

ranges 350-620 nm and 690-1245 nm.

CRS14 solid state Raman shifter for conversion of Nd:YAG laser output

CRS14 solid state Raman shifter for conversion of Nd:YAG laser output is an easy-to-operate device to allow conversion of Nd:YAG laser output of the fundamental and second harmonic. A Ba(NO₃)₂ crystal providing a 1047 см^-1 shift, which is used for radiation conversion. The specially designed cavity pair mirrors allows generation of output radiation with the following parameters:

For fundamental wavelength 1064 nm CRS14 provides:

• a set of mirrors for providing simultaneous generation of the 1st, 2nd, 3rd, 4th and 5th Stokes radiation components
• a telescopic system to ensure optimum power densities in a Ba(NO3)2
• a second harmonic generator (KTP, BBO, LBO) to extend the number of output wavelength

CRS14 solid state Raman shifter for conversion of Nd:YAG laser output can be combined with another laser operating in the spectral range from 400 to 1800 nm.
