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 NT230 High Energy Broadly Tunable DPSS Lasers

NT230 series High Energy Broadly Tunable DPSS Lasers

Ekspla's  NT230 series lasers deliver high up to 10 mJ energy pulses at 100 Hz pulse repetition rate, tunable over a broad spectral range. Integrated into a single compact housing, the diode pumped Q-switched Nd:YAG laser and Optical Paramteric Oscillator (OPO) offers hands‑free, no-gap tuning from 192 to 2600 nm. With its 100 Hz repetition rate, the NT230 series laser establishes itself as a versatile tool for many laboratory applications, as laser induced fluorescence, flash photolysis, photobiology, metrology, remote sensing, etc.

Due to the innovative diode‑pumped design, NT230 series lasers features maintenance-free laser operation for an extended period of time and improved stability (compared with flash-lamp pumped counterparts).

NT230 series systems can be controlled from a user-friendly remote control pad or/and a computer using supplied LabVIEW™ drivers. The control pad allows easy control of all parameters and features on a backlit system display that is easy to read even with laser safety eyewear.

Due to DPSS pump source, the laser requires little maintenance. It is cooled by a built-in chiller, which further reduces running costs. An OPO pump energy monitor allows monitoring of pump laser performance. A standard feature includes a separate output port for the 355 nm pump beam. Read more.

Ekspla NT200 series Tunable Wavelength NIR-IR Range DPSS Lasers

nt200 series laser 1

Ekspla's NT200 series tunable laser systems integrates into a single compact housing a nanosecond Optical Parametric Oscillator (OPO) and Diode-Pumped Solid–State (DPSS) Q-switched pump laser. Diode pumping enables fast data acquisition at high pulse repetition rates up to 10 kHz (depending on model) while avoiding frequent flashlamp changes that are common when flashlamp pumped lasers are used. Most of the pump lasers do not require water for cooling, thus further reducing running and maintenance costs.

All lasers feature motorized tuning across the specified tuning range. The output wavelength can be set from control pad with backlit display that is easy to read even while wearing laser safety glasses. Alternatively, the laser can be controlled also from personal computer through USB (RS-232 is optional) interface using supplied LabVIEW™ drivers. High conversion efficiency, stable output, easy maintenance and compact size make our systems excellent choice for many applications. Read more.
