Ekspla NL120 Series SLM Q-switched Nd:YAG Lasers

NL120 series high energy SLM Q switched NdYAG lasers 1

Ekspla's  NL120 series electro-optically Q-switched nanosecond Nd:YAG lasers deliver up to 10 J per pulse with excellent stability. The innovative, diode‑pumped, self‑seeded master oscillator design results in Single Longitudinal Mode (SLM) output without the use of external expensive narrow linewidth seed diodes and cavity‑locking electronics. Unlike more common designs that use an unstable laser cavity, the stable master oscillator cavity produces a TEM₀₀ spatial mode output that results in excellent beam properties after the amplification stages.

NL120 series Q-switched nanosecond lasers are an excellent choice for many applications, including OPO, OPCPA or dye laser pumping, holography, LIF spectroscopy, remote sensing, optics testing and other tasks. For tasks that require a smooth and as close as possible to the Gaussian beam profile, models with improved Gaussian fit are available).

The low jitter of the optical pulse with respect to the Q-switch triggering pulse allows the reliable synchronization between the laser and external equipment. The optional second (SH) (for 532 nm), third (TH) (for 355 nm) and fourth (FH) (for 266 nm) harmonics generators provide access to shorter wavelengths.

The laser is controlled by a supplied netbook PC via USB port with application for Windows™ operating system. In addition, the main settings of the laser can be controlled through an auxiliary user-friendly remote control pad. The remote pad features a backlit display that is easy to read even when wearing laser safety eyewear. Read More.

Ekspla NL310 Series High Energy Q-switched Nd:YAG Lasers

NL310 series high energy nanosecond q switched NdYAG lasers 1

High pulse energy Ekspla  NL310 series lasers are targeted for applications like OPO or Ti: Sapphire pumping, material processing and plasma diagnostics. These lasers can produce pulse energies up to 10 J in fundamental wavelength at 10 Hz pulse repetition rate.

For the convenience of customers the NL310 series nanosecond Q-switched laser can be controlled either through a user-friendly remote keypad or USB-CAN port. The remote keypad allows easy control of all parameters and features a backlit display that is easy to read even wearing laser safety eyewear. Software for Windows™ operating system is provided to control the laser from PC. LabView™ drivers are supplied as well, allowing laser control integration into existing Labview™ programs.

The optional second (SH, 532 nm), third (TH, 355 nm), fourth (FH, 266 nm) and fifth (FiH, 213 nm) harmonic generators can be integrated into laser head or placed outside laser head into auxiliary harmonics generator module. Output wavelength switching is done manually. Motorized wavelength switching is available by request. Triggering of the laser is possible from built-in internal or external pulse generator. Pulses with TTL levels are required for external triggering. Laser pulses have less than 0.5 ns rms jitter with respect to Q-switch triggering pulse in both cases. The simple and field proven design ensures easy maintenance and reliable long-term operation of the NL310 series laser. Read more

Ekspla NL940 Series High Energy Temporary Shaped Nanosecond Nd:YAG Lasers

NL940 series nanosecond NdYAG laser

The Ekspla NL940 series main laser feature is output of temporary shaped pulses based on electrooptical modulator driven by programable arbitrary form generator (AWG). Pulse shaping resolution is 125 ps, while maximum pulse length is 10 ns. Start of the system is single mode CW laser. Then light is amplified in fibre amplifier, later AWG driven modulator transmits only required temporal shape and duration pulse which is amplified in diode pumped regenerative amplifier in order to reach energy sufficient to amplify in singly pass flash-lamp pumped amplifiers.

Power amplifier is a chain of single-pass amplifiers where pulse is amplified up to required energy. During amplification spatial beam shaping is emloyed in order to get flat top shape at the output. The second harmonic generator is based on angle tuned nonlinear crystal placed in a heater. Read more.
