Ekspla Atlantic 6 Compact Air-cooled Industrial Picosecond Laser

Atlantic 6 model Compact Air Cooled Picosecond Laser

Ekspla's Atlantic 6 is designed for industrial micromachining applications as a reliable, compact and cost effective solution. Hybrid fiber and DPSS technologies implemented in this model make it also very energetically efficient, which enables air cooling solution for laser head. No water is used inside laser, which means you should not worry about unexpected leakage, regular water replacement or possible chiller failure. Laser head generates only around 150 W of heat, so it required quite simple heat management solutions for system integrators. Laser do not require a chiller or big heat exchanger, so all control and power supply electronics is fit into standard 3U 19-inch rack.

Hybrid technology enables new pulse control features, which are not present in earlier Atlantic series lasers. Atlantic 6 can provide burst of pulses spaced only 25 ns in time, so called seeder burst mode. It is very useful in material processing applications, because in some cases it allows to increase process efficiency or at least provides additional variable parameter for process optimization. Atlantic 6 has broad range of accessible pulse repetition ranges, from single pulse to 1 MHz.

Sophisticated pulse picker provides any required sequence of pulses with high contrasts and perfect pulse to pulse parameters stability. Laser accepts external triggering and emits optical pulses with low jitter, in range of 7 ns RMS, which enables good synchronization with very fast scanning systems, like polygon scanner.

Each Atlantic series laser pass very strict quality assurance procedure. Every single unit is checked for vibrations resistance, tested at different environment temperature and humidity conditions, treated by extreme temperatures (up to 70 °C). Before shipment multiple external and internal laser parameters are measured and checked with technical requirements. This costs us time and resources but we believe this is necessary to guaranty unprecedented laser quality and trouble free operation at customer side. Our engineers are always ready to collaborate with system integrators providing valuable advices and small laser optimizations according to integrators needs.

Ekspla SL212 Series SBS Compressed Picosecond Nd:YAG Lasers

SL212 series SBS compressed Q switched NdYAG Laser 1

Ekspla's  SL212 laser is excellent solution for applications, where high energy picosecond pulses are needed. In contrary to conventional mode-locked lasers the SL212 series lasers use different method of generating short pulses based on backward-stimulated Brillouin scattering (SBS). Diode pumped passive Q-switched single longitudinal mode (SLM) nanosecond generator is the heart of the system. It provides nanosecond optical pulse that is later compressed during SBS in a special cell.

Pulse compressor consists of optical guiding system and SBS-cell. SBS cell is designed for safe and longlife maintenance free operation. A linearly polarized light pulse from master oscillator passes through QWP and is focused into SBS-cell by lens. Focusing is arranged in the way to compress the pulse via SBS process. The backscattered Stokes pulse, as its phase is reversed, strictly repeats the path of pump pulse in the opposite direction and with a reversal divergence. The compressed pulse is guided into the amplification stage using polarizer and mirror.

After SBS compression, pulse is directed to multi-pass flashlamp pumped power amplifier system, providing high-energy pulses. SL212 model lasers use multi-pass amplifier system which is based on laser chamber containing Nd:YAG rod pumped by two flash lamps. For smooth obtaining output beam profile pre-amplifier and double-pass amplifier layout is used in SL212 series lasers. Power amplifier includes optical components arranging passes through the active element. Aperture is employed to prevent the returning depolarized radiation from getting back into the amplifier.

Thermocontrolled harmonics’ generators, based on angle-tuned non-linear crystals and harmonic separation optics are available as standard options. Fundamental and second harmonics are separated and has a single output port. Harmonics’ crystals mounted in temperature‑controlled heaters. Pulse compression during SBS, is a simple and cost effective way for generating high power picosecond pulses. In addition to it, SBS compression allows generation of pulses with exceptional pulse duration range: from 150 ps up to 1000 ps. A power supply and water/water type cooling units, placed in standard 19” rack, requires a little space under the user’s optical table. Read more.

Ekspla SL330 Series SBS Compressed Picosecond Nd:YAG Lasers

Picosecond SBS compressed high energy NdYAG lasers SL330 series 2

Ekspla's SL300 series lasers are an excellent solution for applications that require high energy picosecond pulses. Pulse compression during backward‑stimulated Brillouin scattering (SBS), used in EKSPLA SL300 series lasers, is a simple and cost‑efficient way to generate picosecond pulses, with the unique capability of producing pulses with tunable duration.

An electro-optically Q-switched Single Longitudinal Mode (SLM) nanosecond generator is the heart of the system. Instead of external narrow linewidth diode lasers, the selective properties of Fabry-Perrot etalon, and a laser cavity are used to produce SLM pulses with a smooth temporal envelope. In scientific literature this method of generating SLM pulses is known as a selfseeding technique.

Pulse compression is done in a SBS‑cell. Depending on the geometry of interaction, a pulse with duration in the 170 – 1500 ps range can be produced. Pulse duration can be tuned in discrete steps when a variable pulse duration option (-VPx) is installed. After SBS compression, the pulse is directed to a multi-pass power amplifier system for amplification to up to 500 mJ energy.

Temperature controlled harmonics generators, based on angle-tuned KD*P and KDP crystals and harmonic separation optics, are available as standard options. Each wavelength has a separate output port.

A power supply and cooling units are placed in a standard 19” rack that requires little space under an optical table. The very low jitter of the optical pulse relative to the Q-switch triggering pulse ensures reliable synchronization of the laser with external equipment. For customer convenience the laser can be controlled from a user-friendly remote control pad or RS232 interface. The remote pad allows easy control of all laser parameters and features a backlit display that is easy to read even when wearing laser safety eyewear. Alternatively, the laser can be controlled from a personal computer with supplied software for a Windows™ operating system. LabView™ drivers are supplied as well. Read more
