1. Laser Safety.
Laser safety warnings:
The lasers devices described hereafter emit visible/invisible light (@640nm to 1650nm)
power. They are safe to operate, provided the user complies with following safety
procedures:
a) Post warning sign around laser operating area to alert those present.
b) Keep all unauthorized personnel out of the area where B & W TEK's laser is operated.
c) Whenever the laser is running and the beam is not in use, it is good operating practice to
mechanically block the emission path.
d) Never look directly into the laser source or scattering laser light from any reflective
surface. Never sight down the beam into the source.
e) Maintain experimental setup at low heights to prevent inadvertent beam-eye contact.
f) As a precaution against accidental exposures to the output beam or its reflection,
operators should wear laser safety glasses attenuated to the wavelength being generated.

2. Operation:
The B & W fiber coupled diode laser is simple to operate. The light output is almost
instantaneous after the power supply is energized.
Note:
A time delay of approximately 5-10 sec is incorporated in the laser driver in accordance to
safety regulations. There are no adjustments for the user.
Warning:
Use of controls or adjustments or the performance of procedures other than those specified
herein may result in hazardous radiation exposure. It will also void the warranty.
Operational Procedure:
a) Make sure that the remote control connector is plugged in and the remote control circuit
has been completed.
b) Connect the power cable to power service outlet.
c) Check to see that the shutter (cap) is removed from the fiber connector.
d) Check to see the laser current is not applied. Laser power adjustment knob is turning all
the way counterclockwise.
e) Press the power switch. The power indicator will be on.
f) Turn the emission key switch to the ON position (in ON position, the key can not be
removed from the key-lock) and the laser driver will be powered. The emission indicator
will turn on and laser emission may be expected from the aperture in 5-10 seconds.
g) Slowly turn the laser current adjustment knob clockwise to the desired position. The laser
output will be set to the desired power.
h) To turn off the laser, turn the knob counterclockwise to the end, turn off key-switch, turn
off the power switch.
Modulation:
A Standard TTL signal can be applied to the laser through the BNC receptacle on the front
panel. The laser output goes to zero when the applied TTL signal is low, to the set power
when the applied signal is high (or no connection). The modulation rate can be from DC to
20KHz.

WARNING:
DO NOT LOOK DIRECTLY INTO THE LASER. LASER RADIATION IS HAZARDOUS TO
THE EYES. AVOID DIRECT EXPOSURE TO THE BEAM.
3. CDRH Compliant System
The BWF-1 laser systems, which are certified to be in compliance with Class IIIb, are equipped
with keylock switch, remote control connector, laser radiation emission detector, emission time
delay (in the laser driver), a beam attenuator (shutter), and appropriate warning labels. The
following labels were designed to warn the user of potential hazard.
