Laser Safety in Entertainment Applications
By James Stewart, CLSO High power lasers are routinely used in entertainment environments as a special lighting effect. Historically such lasers could only be used in situations where the budget, infrastructure, (namely power supply and cooling), and space permitted. In recent years, however, these barriers have disappeared with the proliferation of low-cost solid-state laser light […]
