Pulsed Dye Lasers

Pump Laser Power: 20mJ-1000mJ
Wavelengths: 330nm-900nm

NarrowScan

The NarrowScan pulsed dye laser series is based on a resonator design with a very narrow line width (<0.04cm-1) that has been optimised in design and specifications by laser experts over many years and can now be used with pump laser pulses as short as 4ns. The laser has very rigid and massive middle and side plates, ensuring a very high stability in the oscillator and pre-amplifier.

NarrowScanK, a compact version is also available.

NarrowScan High Rep (kHz)

The NarrowScan series with polarisation matched oscillator is ideal for multi-kHz, Q-switched pump sources. The high power dye laser output with high spectral purity and stability can be frequency doubled with high conversion efficiency.

CW Lasers

Wavelengths: 400nm-1000nm

CW Ring Laser

The carefully designed and optimised single mode ring resonator guarantees, in any configuration, high performance, stability and easy operation.

Ring Laser Options

• Broadband Ring Laser
• Passively Stabilised Scanning Single-Frequency Ring Laser
• Actively Stabilised Scanning Single-Frequency Ring Laser
• Digital Scan Generator
• Control Box

CW Standing Wave

This dye laser is based on the exchange unit for the Coherent 699 ring laser RDU 10 (nozzle holder and pump mirror adjustment, available from Warsash Scientific). The laser is easy to handle. By an adjustment with micrometre screws a very high reproducibility is guaranteed. The laser is mounted on a 50mm invar rod and the dimensions allow a later installation of the etalon for single mode operation. It consists of a 3-mirror-resonator, wavelength tuning is done by rotation of the Lyot-filter.

Laser Dyes

Wavelengths: 248nm-532nm

Warsash Scientific offer a broad range of laser dyes to cover all desired wavelengths. We can provide solvents in laser quality, which are the optimum solvents for Coumarine, Rhodamine and Cyanine dyes because of their high polarity. The high viscosity of Ethylene glycol shows to be an advantage for the use of cw-dye lasers.

As a special service, Warsash Scientific can provide ready-to-use dye solutions, which are made individual on customer request.

Important Notes

• The dyes have a better durability as a dry powder than as solution.
• Take care, that your dye solution contains no solid particles before the use. Often an ultrasonic bath helps to solve the dye.
• At a change of dye to another wave length the dye circulator must be flushed with clean solvent. Otherwise the efficiency can be reduced or destroyed by dye rests.
• Handle all dyes and solvents with care! A lot of dyes (also as solution) are known as hazardous or irritating. The solvents can carry the dyes through the skin into your body (e.g. Benzyl alcohol, DMSO, Dioxan, Methanol) Always wear rubber gloves, protecting masks, goggles and clothes when weighing and solving the dyes. In case of skin contact wash with plenty of water.
• Please, make yourself clear, which solvents are combustible and take care to avoid any danger.
