Laser Pulse Extender

The ELS-PE-300 laser pulse extender provides a compact, turnkey method of extending laser pulse durations by over an order of magnitude. It is optimized to accept input pulses in the 10-20 nanosecond regime and optically stretch these without distortion or loss of coherence. Energy throughput efficiency is as high as 75%. The final pulse duration can be factory set in 20 nsec increments, anywhere between 20 and 200 nsec.

Several types of lasers (e.g. excimer, Nd:YAG) produce output pulses in the 10-20 nsec range. However, a number of applications require that the pulse be stretched in order to achieve optimum system performance. For example, the high peak power can cause optical damage problems in applications requiring remote fiber delivery. The traditional method of pulse stretching uses homebuilt optical delay lines, which can be cumbersome, inefficient, and may also require frequent realignment. The new laser pulse extender is designed to meet the needs of both scientific and industrial applications.

Several standard models are currently offered, which are optimized for use with excimer, Nd:YAG, copper vapor, or dye lasers. Customized versions are also available for use in other wavelength domains.
