SOLID-STATE RAMAN SHIFTER

Request a quote

The Solid State Raman Shifter LZ series uses innovative technology Ba(NO3)2 (shift 1047 cm-1) and KGdWO4 (shift 767.3 and 901.5 cm-1) crystals. The crystals?unique properties allow their application for Raman frequency conversion ranging from VIS to IR. The nonlinear crystal placed in the optimized cavity ensures high conversion efficiency of the the pump radiation to the 1st, 2nd or 3rd order Stokes, alongside with low generation thresholds. Upon your order mirrors can be installed into the LZ221 Shifter for obtaining definite Stokes, as well as for receiving the multi-line output (generating several components simultaneously) with the total conversion efficiency more than 50%. The design of this device minimizes the needs for user adjustments and allows to easily replace cavity mirrors while re-aligning the Raman Shifter from one wavelength to another.

LZ221

Solid-state Raman Shifter Model LZ221

Unlike gas Raman Shifters using high pressure cells, the LZ221 is characterized by complete safety in operation and low operating densities of pump radiation, what leads to additional advantages and facilitates the operation.
