• Ekspla NL200 Series Compact Q-switched DPSS Lasers

    NL200 series nanosecond compact Q switched DPSS laser 1

    Ekspla's  NL200 series DPSS Q-switched nanosecond lasers offer high pulse energy at kHz repetition rates. End-pumped design makes this laser compact and easy to integrate. Harmonic generation modules for 532 nm, 355 nm, 266 nm and 213 nm wavelengths can be combined into one module, easily attached to the laser frame.

    Featuring short pulse duration, variable repetition rate and external TTL triggering, nanosecond diode pumped NL200 series Q-switched lasers are excellent cost effective sources for specific applications like pulsed laser deposition, ablation through mask or intravolume marking of transparent materials, when higher pulse energy is required. Excellent energy stability and a wide range of wavelength options make this laser a perfect tool for spectro­scopy and remote sensing applications. Mechanically stable and hermetically sealed design ensures reliable operation and long lifetime of laser components. Read more.

  • Ekspla NL220 Series High Energy kHz Pulsed Q-switched DPSS Nd:YAG Lasers

    NL220 series nanosecond Q switched DPSS NdYAG lasers 1

    Ekspla's  NL220 series diode pumped Q-switched lasers produce up to 30 mJ at 1000 Hz  pulse repetition rate. The laser is designed to produce high intensity, high brightness pulses and is targeted for applications like OPO, Ti:sapphire or dye laser pumping, nonlinear spectroscopy, material ablation, micromachining, and other tasks.

    Employing electro-optical type of Q-switch allows the master oscillator to produce pulses with a short pulse duration of 6 ns, nearly TEM₀₀ beam profile and nearly diffraction-limited divergence. The M² factor of the beam is typically less than 2.5.

    Laser cooling uses a closed loop chiller, thus eliminating the need for external cooling water, and reducing running costs. For PIV applications a double-pulse version of this laser is available.

    Angle-tuned LBO and/or BBO crystals mounted in temperature stabilized heaters are used for optional second, third or fourth harmonic generation. The harmonics separation system is designed to ensure a high spectral purity of radiation directed to separate output ports.

    For customer convenience the laser can be controlled from a user-friendly remote control pad or USB interface. The remote pad allows easy control of all parameters and features a backlit display that is easy to read even 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.

  • Ekspla NL230 Series High Energy Q-switched DPSS Nd:YAG Lasers

    NL230 series nanosecond Q switched DPSS NdYAG lasers 2

    The Ekspla  NL230 series diode-pumped Q-switched lasers produce up to 150 mJ at 100 Hz or up to 190 mJ at 50 Hz pulse repetition rate. Diode pumping allows maintenance-free laser operation for an extended period of time (more than 3 years for an estimated eight working hours per day). The typical pump diode lifetime is more than 1 billion shots.

    Lasers are designed to produce high-intensity, high-brightness pulses and are targeted for applications such as material ablation, remote sensing, OPO, Ti:Sapphire or dye laser pumping. Due to an electro‑optical Q-switch, the master oscillator generates short duration pulses in the 3 – 7 ns range. The oscillator cavity optical design features a variable‑reflectivity output coupler, giving a low-divergence laser beam. A closed-loop TEC based chiller is used for laser cooling, eliminating the need for external cooling water and reducing running costs. Angle-tuned non-linear crystals mounted in temperature stabilized heaters are used for optional second, third or fourth harmonic generation. The harmonics separation system is designed to ensure radiation with a high spectral purity and to direct it to the separate output ports.

    For customer convenience the laser can be controlled via a user‑friendly remote control pad or a USB interface. The remote pad allows easy control of all parameters and features a backlit display that is easy to read even through laser safety eyewear. Alternatively, the laser can be controlled from a personal computer via supplied Windows™ compatible software. LabVIEW™ drivers are also included with each laser. installation package. Read more.

  • Ekspla NL740 Series Ultrastable Nanosecond Laser

    NL740 tunable pulse duration NdYAG lasers

    The main feature of the Ekspla  NL740 series is the output of ultra-stable tunable duration (2 – 10 ns) narrow bandwidth nanosecond pulses based on temporally driven CW diode laser seeder and amplification stages.

    Start of the system is the single mode DFB laser with temporal output power modulator. Then light is amplified in diode pumped regenerative amplifier in order to reach energy sufficient to amplify in double pass diode pumped amplifiers. Power amplifier is a chain of double pass amplifiers where pulse is amplified up to required energy. Before amplification spatial beam shaping is employed in order to get flat top shape at the output. The harmonic generators are based on angle tuned nonlinear crystals placed in a heater. Read more.
