PL2210 Series - Diode-pumped Nd:YAG Picosecond Lasers

The air-cooled "all solid-state" DPSS Nd:YAG lasers of the PL2210 series are turn-key systems with high stability and excellent beam quality which offer up to 5 mJ pulse energy and up to 1 kHz repetition rate. In combination with very low jitter values, the PL2210 lasers are ideal for time-resolved and pump-probe spectroscopy but also for OPO/OPA pumping and material processing applications.

PL2210 series diode-pumped, air-cooled, mode-locked Nd:YAG lasers provide picosecond pulses at a kilohertz pulse repetition rate. Short pulse duration, excellent pulse-to-pulse stability, superior beam quality makes PL2210 series diode pumped picosecond lasers well suited for many applications, including material processing, time-resolved spectroscopy, optical parametric generator pumping, and other tasks.

Flexible design

PL2210 series lasers offer a number of optional items that extend the capabilities of the laser. A pulse picker option allows control of
the pulse repetition rate of the laser and operation in single-shot mode. The repetition rate and timing of pulses can be locked to an external RF source (with –PLL option) or other ultrafast laser system (with –FS option). The laser provides a triggering pulse for synchronization of the customer‘s equipment. A low jitter SYNC OUT pulse has a lead up to 500 ns that can be adjusted in ~0.25 ns steps from a PC. 

Up to 400 μs lead of triggering pulse is available as a PRETRIG standard feature that is designed to provide precise, very low jitter trigger pulses for a streak camera.

Built-in harmonic generators

Automated angle-tuned non-linear crystals mounted in temperature stabilized heaters are used for second, third and fourth high spectral purity harmonic generation.

Simple and convenient laser control

The laser can be operated from personal computer through USB (RS-232 is optional) interface using supplied LabVIEW™ drivers or from remote control pad with backlit display that is easy to read even while wearing laser safety glasses.

Standard Feature PETRIG

Provides low jitter pulse for streak camera triggering with lead/delay in -400…600 μs range and <10 ps rms jitter.

Option P80

Provides 80 ps ± 10 % output pulse duration. Inquire for pulse energy specifications.

Option P20

Provides 22 ps ± 10 % output pulse duration. Inquire for pulse energy specifications.

Option PC

Allows reduction of the pulse repetition rate of the PL2210 series laser by integer numbers. Single shot mode is also possible. In addition, the –PC option reduces the low-intensity quasi-CW background that is present at laser output at 1064 nm wavelength. Please note that the output of fundamental wavelength and harmonics will be reduced by approx. 20% with installation of the –PC option.
