The HLSR series of Ruby lasers were specially developed for Holography applications. The high pulse energies (up to 10J) and even beam profile thanks to a spatially filtered oscillator offer excellent illumination, and Ruby’s inherently narrow bandwidth mean that coherence lengths over 1m are achieved without the need for expensive seeding or mode-locking techniques. An upgrade is available giving over 7.5m of coherence - more details are available in our downloads area.

For interferometry applications, fully adjustable double-pulsing is offered as standard. The relatively long fluorescence lifetime of Ruby means that pulse separations up to 800μs are available.  More pulses are possible - we have supplied lasers with as many as 10 individually adjustable Q-switched pulses.  The HLSR range comprises 3 models, HLSR20, HLSR30 AND HLSR40. Each uses the same oscillator design but with different amplifier configurations to give outputs of 1J, 3J or 10J single pulse.
