EKSPLA has 4 product lines: scientific lasers and laser systems, industrial lasers, laser spectroscopy, and laser electronics components.[8] The company manufactures and supplies photonic products and services for OEM and R&D applications.
Since its foundation, the company was manufacturing only flash-lamp pumped lasers. But as diode pumping results in better overall efficiency and beam quality, a decision was made to replace them with diode-pumped lasers. Currently the EKSPLA laser product line comprises mainly tunable wavelength and diode-pumped lasers.
If classified by pulse duration, the company manufactures femtosecond, nanosecond and picosecond lasers.[9]
Most common EKSPLA lasers applications:
EKSPLA's portfolio includes femtosecond lasers as part of its industrial product line. The FemtoLux 30, a low-maintenance ultrafast laser, serves as a reliable solution for a variety of micromachining tasks with its versatile features.
The laser incorporates several advanced technologies developed by EKSPLA's engineers: GHz burst modes, Pulse-on-Demand function; it is not only efficient and versatile but also easy to use:
- GHz burst modes: This is especially important for the semiconductor industry, where glass can be processed more precisely, at lower cost, and faster. Thanks to the patented GHz burst modes, the FemtoLux 30 laser is the only one on the market with unmatched flexibility in selecting burst configurations, ranging from two to thousands of pulses per burst. This flexibility has been applied to drilling deep, small-diameter holes in glass.
- The Pulse-on-Demand function allows for precise maintenance of identical distances between adjacent pulses, even when the scanning speed of the laser beam dynamically changes, preventing excessive pulse overlap and maintaining homogeneous structures. The PoD function is essential for fast material processing while maintaining quality. This is achieved by keeping equal distances between adjacent pulses, even as the laser beam scanning speed dynamically changes. This way, excessive pulse overlap is avoided, and the homogeneity of the processed structure is preserved.
- Broad pulse duration tuning. The proven patented Active Fiber Loop technology for GHz burst shaping has been adapted for flexible pulse duration tuning – from several hundred femtoseconds to nanoseconds. This feature, along with others, extends the versatility of the FemtoLux 30 and makes it possible to combine nanosecond, picosecond, and femtosecond laser sources into one – FemtoLux 30 with broad pulse duration tuning, covering different duration ranges and reducing costs (one system instead of three).
It is also the first ultrashort pulse (USP) laser in the market with novel direct refrigerant cooling (DRC) method, which means, no water is used, the systems maintains high cooling efficiency and shows over lower power consumption compared to water cooling USP lasers.
The FemtoLux 30 compact design integrates both the laser head and power supply into a small footprint, facilitating easy integration into industrial setups.
It is used for micromachining, glass, sapphire and ceramics micro processing, microelectronics manufacturing, glass intra volume structuring, micro processing of different polymers and metals, LCD, LED, OLED drilling, cutting and repair.
EKSPLA Electronics group delivers electronics devices specifically tailored for laser applications for laser manufacturers and scientists.
- Laser diode drivers are critical components in the operation of laser diodes, providing the necessary electrical current and control to ensure optimal performance and longevity. Laser diodes are versatile and widely used in various applications, including but no limiting lasers for science, industry and medical applications. However, these sensitive devices require precise current control to function correctly and to avoid damage.
- Pockels Cell Drivers & HV Power Supplies. A Pockels cell driver is an essential component in various optical systems, particularly in applications involving laser modulation and Q-switching. These drivers are responsible for controlling Pockels cells, which are electro-optic devices used to modulate the polarization state of light passing through them. The drivers provide the high-voltage electrical pulses needed to activate the Pockels cells. These pulses induce the electro-optic effect in the crystal, allowing for rapid and accurate modulation of the laser beam.
- Laser Synchronization Modules & Pulse Delay Generators The SY4000 module is a timing generator dedicated to synchronizing various laser components such as AOM drivers, Pockels cell drivers, laser diodes, flash lamp drivers, detectors, and data acquisition systems. Standard applications include:
- Passive or active mode-locked, Q-switched lasers, pulsed or QCW
- Data acquisition system triggering
- General-purpose pulse generation
- Precise system clock source
- Converting laser pulse trains to a clean clock source
- Performing all the above functions simultaneously
- Crystal Ovens. In laser applications, certain optical crystals need to be heated during operation to maintain their performance, enhance their properties, or prevent damage. That are particularly nonlinear optical crystals like KTP, BBO, LBO, acousto-optic crystals TeO2, electro optic crystals KDP, DKDP and others. Devices so called crystal ovens are used to keep the crystals at certain precise temperature.
