• Continuous operation mode

• Built-in harmonics

• Turn-key operation

• Remote control

The STLQ-115 is an ultra-compact model of air-cooled Nd:YAG laser for applications requiring compact and undemanding laser source.

Due to application of original high-efficiency heat exchanger the STLQ-115 laser unlike most air-cooled laser models can work continuously with PRR up to 3Hz and cyclically with PRR up to 5Hz. The above operating modes are realised at output energies conventionally attained at water-cooled lasers.

The STLQ-115 laser provides up to 90mJ output pulse energy at the fundamental with possibility of further conversion of IR radiation into the second harmonic as well as into the third or fourth harmonic.

All the harmonic generators are built-in and temperature stabilised. This peculiarity together with optimised rigid laser head design ensures output radiation long-term stability comparable to that of standard laboratory lasers.

Unlike most compact lasers using DKDP-based Pockels cells, the STLQ-115 incorporates LiNbO3 electro-optical Q-Switch. Such Q-Switch is not hygroscopic and retains its parameters within a wide temperature range and ensures reliable and stable laser operation.

Dust-proof laser head design allows to align main optical components without removing the cover that increases their life in the field.

To reduce your time expenses on routine service of the STLQ-115 laser we use only long lifetime flash lamps by Heraeus Noblelight Ltd. Besides, the flash lamp replacement procedure is elementarily easy even for a unskilled user.

Absence of water cooling system gives to the STLQ-115 laser a number of essential operational advantages:

• Footprint of both the laser head and power supply is considerably reduced.

• Integration of the laser into different mobile systems is facilitated.

• Technical reliability of the device operation is increased.

The STLQ-215 laser is built on the basis of a model produced for aerospace industry and combines excellent beam quality required for advanced scientific research with a highest reliability of industrial equipment.

Original and reliable optical scheme ensures compensation of both astigmatism and thermooptical distortions and places at your disposal laser radiation of the highest quality.

One more peculiarity of the laser optical scheme is that all the components operate at loads considerably lower than the admissible values. Such a smooth operation mode not only increases life time of the components but also ensures unique operational reliability of the whole laser. As a result, you can use the STLQ-215 laser for your experiments day-to-day and year-to-year having forgotten about repairs and other unpleasant operation costs.

All the laser optical components are installed on a rigid base fixed to the housing with specially developed dampers. Due to this, mechanical vibrations and housing stress no way influence the quality of the cavity alignment.

All the critical components of the laser are thermally stabilised which in combination with vibration-proof design ensures unsurpassed long-term output radiation stability. The efficient thermostats used in the STLQ-215 ensure warm-up time of less than 10min.

To reduce your time expenses on routine service of the STLQ-215 we provided flash lamp life time of more than 50 million pulses and foreseen easy and quick procedure of its replacement.

It should be noted that the laser design allows to replace the flash lamp without removing the laser head upper cover. Such a technical solution considerably reduces risks of the optical components contamination as well as increases operational reliability of the device.

Closed-loop water-to-air cooling system is integrated into a compact single-phase laser power supply which can be controlled both from PC and via the remote control unit.

The STLQ-215-D is built on the basis of a laser produced for aerospace industry and combines excellent beam quality required for advanced scientific research and a highest reliability of industrial equipment.

The design of conventional lasers generating dual pulse is based either on combining two lasers or on successive generation of nanosecond pulses by one active element during one flash lamp discharge pulse. The first solution allows to build a system with the maximum capabilities for the user but leads to increase of its cost and dimensions. The second approach allows to create low-cost and compact systems but leads to reduction of each pulse energy and of laser beam profile worsening and stability as well as limits the delay range between the pulses.

The STLQ-215-D design demonstrates advantages of both the variants but eliminates their disadvantages: output radiation is generated by two separate cavities while both the Nd:YAG rods are installed in one pump chamber and are pumped by one flash lamp. Both the cavities are integrated into a common laser head controlled by a common power supply that provides to the user minimum dimensions and convenience in controlling dual pulse parameters.

Original and reliable optical scheme ensures compensation of both astigmatism and thermooptical distortions and places at your disposal laser radiation of the highest quality.

One more peculiarity of the laser optical scheme is that all the components operate at loads considerably lower than the admissible values. Such a smooth operation mode not only increases life time of the components but also ensures unique operational reliability of the whole laser. As a result, you can use the STLQ-215-D laser for your experiments day-to-day and year-to-year having forgotten about repairs and other unpleasant operation costs.

The system consists of two modules – the DPSS pulsed laser model STQX-500 (at 1064nm) and removable module for any harmonic generator model STQH (at 532nm, 355nm, 266nm). So, the customer can work either with 1064nm or with any harmonic in depend on applications. The removable harmonic generator module can be fix at STQX-500 output or remove by manual.

Our DPSS lasers do not require visit of engineer for installation procedure due to special technical design that exclude the possible misalignment of the laser’s optical scheme. The end user can start to work STQX-500 laser by himself without any troubles. All necessary information for working is presented in the user manual and video guide instruction. Even the specialist without technical skills can start and work with QX500 laser comfortable.
