I thought that the 1W RGB laser light systems would be a good base for comparison, so I drew a small chart showing the price development of the smallest, analogue modulated RGB white light system, that was available from Laserworld in the very year (except the gas laser system – which is included for comparison purposes only). Data source are the historic price lists of Laserworld and my experience. Prices shown are net retail prices, so of course dealer pricing was better – at least for products from 2009 on. For gas laser systems there wasn’t that much discount in the past.
One more thing to mention is that the show laser light systems also grew in technology – and thus in visibility: Whereas the gas laser system in 2005 still was a massive apparatus with water cooling and enormous power consumption, the smaller solid state laser light systems that were offered by Laserworld didn’t have these disadvantages any more – they were all air cooled devices. The first solid state RGB white light laser systems were usually equipped with green and blue DPSS lasers (where blue was at 473nm – so more a cyan color), and red already was created with diode laser sources (however, there were also DPSS red laser solutions in use).With the development of the 637nm red diodes, the price per diode raised again, but the visibility was much better, so were the beam specifications. That’s why this color spectrum took over for the entry-level semi-pro systems. Soon afterwards the DPSS 473nm cyan-blue DPSS were substituted with 410nm ultra-dark blue lasers, but this era didn’t last long, as very soon the 445nm royal blue diodes became very much cheaper and thus took over as standard blue laser source in modern show laser light systems. The blue diode lasers were developed further, so they now run at 450nm, but the general technology behind is the same.
The chart above shows the price development of a low level 1W RGB white light show laser light system, however the development of the possible overall laser powers per show laser light projector increased a lot through the years. Nowadays more than 110W white balanced RGB laser light is possible, even for graphics projections, and there is more to be expected very soon. Laserworld and their subsidiaries continuously drive the product and technology development – some great new steps to further milestones in laser light development are to be expected.
