Laser Theory And Procedures

Question 1

What are the laser standards?

Answer 1

1064 nm wavelength
PRF 1111 - 1788
Lower code equals higher rate

Question 2

What kind of laser reflections are there?

Answer 2

Specular reflection
Diffuse reflection

Question 3

What are the laser planning considerations?

Answer 3

All planning is from the LTL
Add safety zone plus/minus 10°
Best acquisition plus/minus 45°
Safe acquisition plus/minus 60°
Outside plus/minus 60° is dangerous

Question 4

What are the needs for effective laser marking?

Answer 4

Line of sight from LTD to TGT

Line of sight from weapon and or aircraft to target

Same wavelength

Same laser code

Within angler restrictions

Consider strong surface wins

Question 5

What is beam divergence?

Answer 5

The laser beam will spread slightly with increased distance to the target

The measure of how the size of the beam increases with the distance is called beam divergence expressed mrad

Beam divergence is 0.3 mrad

Question 6

What possible problems is there with laser employment

Answer 6

Overspill
Podium effect
Entrapment

Question 7

What is overspill?

Answer 7

May occur when the beam size is larger than the area of the target

May be compensated by a slightly lower aiming point, causing some Underspill often easier to handle

Weapons set to last logic making the weapon hit the overspill rather than the target

Question 8

What is the podium effect?

Answer 8

The target itself obscures the laser energy from the weapon or aircraft

Question 9

What is entrapment?

Answer 9

The laser energy is locked into a cavity of the target

For a laser handover, this may be solved by tapping slightly on top of the LTD to jiggle the beam until the sensor acquires the spot

Question 10

Laser brevity terms

Answer 10

10 seconds equals standby for laser on call

Laser on equals start, laser designation

Lazing equals the speakers firing the

Shift equals shift, laser either to a target or from a offset position to target

Spot equals acquisition of laser designation

Cease laser equals discontinue lazing

Negative laser laser energy has not been acquired

Deadeye equals LTD in operative

Stare equals Q the latest spot search/tracker function on a specific laser code in relation to the specified reference point

Question 11

What is NOHD?

Answer 11

Nominal ocular hazard distance

• The distance along the axis of the unobstructed beam from the laser to the human eye beyond which the iridium or radiant exposure during normal operation is not expected to exceed the applicable MPE

Question 12

What is MPE?

Answer 12

Maximum permissible exposure

• The level of laser radiation, which Persson may be exposed without hazardous effect or adverse biological changes in the eye or skin

Question 13

Name the laser, safety considerations?

Answer 13

Never look directly into a laser, regardless of the laser classification

Treat a laser as you would a weapon

Never point a laser at a individual unless in your intended

No binary use while lacing unless filter

Always wear laser eye protection when down rage of a laser or where specular reflections are present

When finished with the laser always turn off disarm and replace lens cover

Personnel stay behind the laser while in use
