1 All powers are listed in Watts. Guaranteed power specifications for standard systems are indicated in bold print. All power specifications, except multiline visible and IR, are TEM00.

2 All beam specifications are measured at specified output powers at 514.5 nm for argon lasers and 47.1 nm for krypton lasers.
3 Beam diameter is measured at the output-coupler mirror.
4 Inside the resonator, the beam waist is located at the flat high reflector. The long-radius output coupler acts as a weak lens to transfer the output-beam parameters. The values listed for beam divergence, beam waist diameter and beam waist location take into account the weak lens effect. The value for beam waist location is measured from the output coupler toward the high reflector.
5 Maximum peak variation over any 30 minute period after a 2-hour warm-up.
6 Measured with a 10 Hz to 2 MHz photodiode driving a resistive load at
514.5 nm for argon systems and 647.1 nm for krypton systems.
