PL2250 series lasers set a new standard in high pulse energy mode-locked picosecond lasers. Their innovative and cost-effective design improves laser reliability and reduces running and maintenance costs.

Innovative design

The heart of the system is a diode pumped solid state (DPSS) master oscillator placed in a hermetically sealed monolithic block. The flashlamp pumped regenerative amplifier is replaced by an innovative diode  pumped regenerative amplifier. Diode pumping results in negligible thermal lensing, which allows operation of the regenerative amplifier at variable repetition rates, as well as improved long-term stability and maintenance free operation.

The optimized multiple-pass power amplifier is flashlamp pumped and is optimized for efficient amplification of pulse while maintaining a near Gaussian beam profile and low wavefront distortion. The output pulse energy can be adjusted in approximately 1% steps from 1 mJ to nominal output, at the same time as pulse-to-pulse energy stability remains less than 0.8% rms at 1064 nm.

Angle-tuned KD*P and KDP crystals mounted in thermostabilised ovens are used for second, third and fourth harmonic generation. Harmonics separators ensure the high spectral purity of each harmonic directed to different output ports.

Built-in energy monitors continuously monitor output pulse energy. Data from the energy monitor can be seen on the remote keypad or PC monitor. The laser provides several triggering pulses for synchronization of the customer&lsquo;s equipment. The lead or delay of the triggering pulse can be adjusted in 0.25 ns steps from the control pad or PC. Up to 1000 &mu;s lead of triggering pulse is available as a pretrigger option.

Precise pulse energy control, excellent short-term and long-term stability, an up to 50 Hz repetition rate makes PL2250 series lasers an excellent choice for many demanding scientific applications.

Simple and convenient laser control

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 while wearing laser safety eyewear.

Alternatively, the laser can be controlled from a personal computer with supplied software for a Windows&trade; operating system. LabVIEW&trade; drivers are supplied as well.

  • 液体中三维贯穿度和速度分布检测方案(粒子图像测速)
    An experimental study has been conducted to study the effect of a swirling crossflow on transversely injected liquid jets. In-house designed axial swirlers with vane exit angles of 30&#176;, 45&#176; and 60&#176; were used to generate the swirling crossflow. Laser Doppler Velocimetry (LDV) results indicate that the axial (Ux) and the tangential (U&#952;) components of the crossflow velocity decrease with increasing radial distance from the center. Also, flow angle (&#968;) of the crossflow is lesser than the swirler vane exit angle indicating that the swirlers did not impart sufficient tangential momentum for the flow to be parallel to the vanes at swirler exit. The deficit in flow angle increased with swirler angle. Water jets were injected from a 0.5 mm diameter orifice located on a cylindrical centerbody that protruded through the hub of the swirler. Particle Image Velocimetry (PIV) was used to study the behavior of the jets. PIV measurements were conducted in multiple cross-sectional and streamwise planes. Mie-Scattering images were col-lated to create three-dimensional representation of the jet plume, which was used to study penetration. In cylindrical coordinate system, the penetration can be described in terms of radial and “circumferential” penetration, where cir-cumferential penetration is defined as the difference in the circumferential displacement of the jet and the crossflow over the same streamwise displacement. Increasing the momentum flux ratio (q) resulted in a higher radial penetra-tion. Increasing the swirl angle reduced radial penetration and increased circumferential penetration. PIV results of the cross-sectional and streamwise planes each yielded two velocity components which were merged to obtain three-dimensional droplet velocity distribution. The three-dimensional velocity distribution yielded further insight into the evolution of the jet plume

  • 空气击穿中阴影成像检测方案(激光产品)
    We present two-dimensional measurements of the laser-induced plasma development and shock wave evolution in air. The breakdown is induced by a Q-switched Nd:YAG laser (&#955; = 1064 nm) with a pulse duration of 4 ns. To study these fast laser-induced phenomena, we have developed a high-speed, two frame shadowgraph method. It enables 2D visualization of a laser-induced event in two time instances, which are delayed by an arbitrary time interval in the range from 300 ps to 30 ns. The established method is based on 30 ps, green (&#955; = 532 nm), and linearly polarized laser pulse, which is split into two orthogonally polarized illumination pulses for direct and delayed illumination of the breakdown area. Exploiting polarization of the probe pulses, we capture two temporally and spatially separated frames with two CCD cameras. Special attention is given to the subsequent data processing, especially to the minimization of the systematic error due to alignment of both images, and to the determination of 2D velocity distribution from the captured image pairs.
