You will be able to concentrate on your work and forget about unpleasant down-time and waiting for service thanks to the industrial design of the LQ215. This laser, specially developed to fit rough industrial operating conditions, perfectly suits for long-term no-failure operation.

You will be sure in precision of your experiments due to the excellent laser beam quality and long-term stability of output parameters ensured by the original optical design of the cavity and fine thermal stabilization of all the critical laser components.

Your day-to-day convenience in operating this laser will be ensured by such features as built-in harmonic generators, PC control over the laser parameters, easiness of flashlamp replacement, closed-loop water-to-air cooling, powering from an ordinary wall mains, small foot-print and others.

You will minimize the expenses on routine service as the LQ215 flashlamp lifetime is more than 60 million pulses which considerably reduces service intervals as well as your expenses on ownership of this excellent device.

HARMONIC GENERATORS

In the standard configuration the LQ215 laser has built-in SHG, THG and FHG. However, upon your request the harmonic generators can be supplied as external stand-alone modules. FiHG is available only as an external unit.

OPO

Upon your request the LQ215 laser can be supplemented with an optical parametric oscillator of the LP600 series. In such a combination you will have a source of continuously tuneable laser radiation within a wide spectral range (from UV to IR).

ATTENUATOR

The laser can be supplemented with a PC controlled attenuator. Upon your choice it can be either a unit optimised for operation at one wavelength or an achromatic attenuator intended for simultaneous attenuation of all the laser harmonics from 266 nm to 1064 nm.

ARTICULATED ARM

A number of applications require quick and flexible laser beam delivery to the research object or the place of measurements. For this an optical fiber can be used but only for delivery of low pulse energy radiation (5-20 mJ). To deliver high-power radiation we offer to supplement the laser with a mirror articulated arm. To minimise losses of laser pulse energy we use special dielectric mirrors with high reflection coefficient simultaneously for 1064 nm and 532 nm.
