Laser diode assembly for laser scanner system

A laser source arrangement for use in a laser instrument of a kind used to transmit a scan pattern to a target which is spaced from the laser instrument, said laser source arrangement comprising:

• light source means for producing a laser beam, said light source means being characterized by astigmatism;
• means for driving said light source means in a pulsed mode having a duty cycle which reduces and controls said astigmatism;
• and
• optics means for correcting said astigmatism and for conditioning said beam so that said beam may be employed by said laser instrument to produce said scan pattern.

A laser source arrangement for use in a laser instrument of a kind used to transmit a scan pattern to a target which is spaced from the laser instrument, said laser source arrangement comprising:

• light source means for producing a laser beam;
• optics means for conditioning said beam to allow said beam to be employed by said laser instrument to produce said scan pattern, said optics means inducing coma into said beam;
• and
• means for correcting said coma induced into said beam.

• light source means for producing a laser beam, said light source means being characterized by astigmatism;
• means for driving said light source means in a pulsed mode at a given duty cycle to reduce and control said astigmatism;
• and
• optics means for correcting said astigmatism and for conditioning said beam so that said beam may be employed by said laser instrument to produce said scan pattern.
