• optical parametrical generation
• sum-frequency generation
• difference frequency generation
• Raman conversion

All devices were developed based on extensive experimental scientific research and mathematical modeling and integrate the most innovative ideas of modern nonlinear optics. Increased reliability and low cost are ensured by the solid-state technology based on up-to-date nonlinear optical crystals, such as BBO, LBO, KTP, DKDP, Ba(NO3)2 , KGdWO4 , etc.
High conversion efficiency, hands-off operation and compact size make these devices an ideal and logical supplement to conventional lasers.

OPTICAL PARAMETRICAL OSCILLATORS

New SOLAR LS OPO systems combine high energy output, extremely wide tuning range with exceptionally easy maintenance and increased reliability.
These OPO systems are developed based on the end user's demands and are highly reliable and easy to operate. The main advantage of the OPO LP series is extremely low minimum required operating pump power densities. Thanks to the original optical scheme the specified parameters are obtained even at low pump intensities and as a result neither crystals nor other optics can be damaged. This feature combined with precise optics mounts and dust protective housing insure perfect reliability and long-term output stability.

BBO OPO system Model LP601

 

The OPO LP series optical design provides high-efficiency output even if it is pumped by standard multimode Nd:YAG lasers. The customer does not have to buy or use complex and expensive TEMoo or single-frequency pump lasers. The maintenance expenses are therefore reduced and the OPO LP series is attractive for every user. Compactness of the OPO saves space at your optical table and allows to easily integrate it into any available laser system.
A set of broadband dichroic mirrors supplied in the standard set with the device allows when it is necessary to separate the idler and the signal waves.

Nd:YAG LASERS HARMONIC GENERATORS

New LG-series of harmonic generators provides efficient output at 213nm, 266nm and 355nm. Compactness and compatibility with any pulsed Nd:YAG laser make these devices the most cost-effective source of UV radiation for various scientific and industrial applications.

Nd:YAG lasers equipped with the LG105 will greatly increase your capabilities and for a lot of applications can eliminate  the necessity for excimer lasers. We apply Solid-State technology which does not uses toxic gases and costs less, giving you the advantage of consistent day-to-day operation and low maintenance. High quality BBO crystal is used in the LG105 as a non-linear element, providing up to 20% conversion efficiency to 213nm. The non-linear crystal is placed in a special cell ensuring long lifetime of BBO without any damages. A harmonic separation system installed in the LG105 provides nearly 100% spectral purity output at 213nm. The LG105 Fifth Harmonic Generator gives you not only high power output but also a possibility of work with the required radiation stability.

SOLID-STATE RAMAN SHIFTER

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.

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.
