4. STLQ Series EO Q-switched Lasers

4.1 Compact Air-cooled Nd:YAG Laser Model STLQ115

Up to 90mJ @ 1064nm and built in harmonic generators 532nm, 355nm, 266nm

FEATURES:

  • No cooling water required
  • Compact & rigid design
  • Excellent beam profile
  • Continuous operation mode
  • Built-in harmonics
  • Turn-key operation
  • Remote control

The STLQ115 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 STLQ115 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 STLQ115 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 STLQ115 incorporates LiNbO3 electrooptical 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 STLQ115 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 STLQ115 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.
  • Operating costs are reduced.

FEATURES:

  • Excellent beam quality
  • Built-in harmonic generators up to 213 nm

  • Reliability of industrial equipment
  • Compact single phase power supply
  • No need for external water

The STLQ215 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

STLQ215 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 STLQ215 ensure warm-up time of less than 10min.

To reduce your time expenses on routine service of the STLQ215 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.

If you plan to use the STLQ215 in laboratory experiments, as a bonus you will get unsurpassed operational reliability and minimization of accompanying expenses.

If you are attracted by the reliability of the STLQ215 laser and you will use it for industrial or field applications, in addition to a highest reliability you get beam quality conventionally available only for high-precision laboratory equipment.

4.3 Dual-Pulse Compact Nd:YAG Laser Model STLQ215-D

Up to 100mJ @ 1064nm and 50mJ @ 532nm in each pulse

FEATURES

  • Excellent beam quality
  • 1064 nm or 532 nm output wavelength
  • Beam pointing stability
  • Dust- and water-proof design
  • Reliability of industrial equipment
  • Compact single phase power supply
  • No need for external water

The STLQ215-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 STLQ215-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 STLQ215-D laser for your experiments day-to-day and year-to-year having forgotten about repairs and other unpleasant operation costs.
