Original optical scheme and design of the LX229 laser embodies more than 20-year experience of SOLAR LS engineers in the field of developing solid-state tunable laser systems.

A new model, LX229, is a simplified version of the high-power tunable Ti:Sapphire laser LX329.

Similar to LX329, the new model provides continuous tuning in the visible and near IR spectral range with output linewidth less than 5 pm. Furthermore, the output pulse energy at the maximum of tuning curve achieves 20 mJ which is sufficient to solve most of scientific tasks.

The LX229 incorporates a built-in SHG and a spectral separation system of the fundamental and second harmonic beams which allows you to change the operating wavelength range quickly and without removing the laser upper cover and performing any additional adjustments.

The LX229 keeps all the advantages of more powerful model LX329: Gaussian beam profile and low divergence. This allows to convert the laser radiation into the UV range efficiently with the external LG312 harmonic generator and to use it for various nonlinear optical applications.

High efficiency of the LX229 operation and harmonics generation is realized at relatively low pump intensities that increases the laser reliability and long-term stability of output parameters.

For your convenience, the LX229 is supplied together with the LQ529BNd:YAGpump laser the parameters of which are specially optimised for such applications. Both the lasers are fixed on a common rigid mounting frame that ensures strict mutual orientation of the devices and mobility of the laser system.

In addition to the standard configurations of tunable systems based on Ti:Sapphire lasers, SOLAR LS also develops and supplies customized tunable laser systems to your specific requirements.

1. The LQ529B pump laser

To obtain the specified parameters of theLX229 SOLAR LS recommend to use the LQ529BNd:YAG laser since it isspecially optimised for such applications.

2. The third and/or fourth harmonic generator

Upon to your request the standard LX229 version can be equipped with the built-in second harmonic generator and/or with the external generator of the third and/or fourth harmonic model LG312.

The LG312 third and/or fourth harmonic generator allows to convert the LX229 Ti:Sapphire laser radiation efficiently into the UV spectral range.

3. Fabry-Perot interferometer

The LX229 can be optionally equipped with intracavityFabry-Perot interferometer for obtaining output linewidth narrower than 5 pm.

4. PC control option

5. Спектрометр SHR

The SHR spectrometer allows to measure the absolute wavelength value with ± 3pm accuracy and to determine FWHM of a spectral line with resolution of 30 000 (λ/Δλ, FWHM) which amounts from 6pm for the UV range to 40pm for the IR range. SHR also provides on-line monitoring of wavelength, FWHM, and spectral line shape in the process of tuning the analyzed wavelength.
