• New wavelengths, higher power/energy, shorter pulses
• Improved power efficiency (lasers may be plugged in wall
outlets)
• Miniaturization: dime size Class 4 lasers (eye and skin hazard)
• High power laser components (exempt from manufacturer
standards - engineering safety features, labels, etc.) may be
“under the radar” of LSO and laser safety programs
• Most of the these components operate within the invisible
near IR retinal hazard range, e.g. 808, 850, 920, 980 nm

• High power (class 4) levels used in fiber optic applications,
e.g. pumping lasers in fiber amplifiers
• Laser output possibly accessible far away from laser source
• “Fiber fuse” effect: occurs in fibers when the power
propagating along the fiber is > 1W
• Multiplexing (combining optical signals)

Keys to a Successful Laser Safety Program
• Active involvement and support of laser users
• Effective oversight by Laser Safety Officer
• Support from management at all levels
A new Laser Safety Page is now available on the RMS website
with additional resources and information.
