Laser diode driver

> Model number: AVO-9A-B-P-P3-SLAA
>
> Description: Laser Diode Driver (Pulsed Voltage) with IEEE-488.2 GPIB
> and RS-232 Computer Control Ports
>
> Polarity: positive
>
> Amplitude: 0 - 140 mA (see footnote 3 on datasheet)
>
> Maximum output of mainframe into 50 Ohms: 10V
>
> Pulse width (FWHM): 2 - 50 ns
>
> Maximum PRF: 50 kHz
>
> -P3-SLAA option: Provides an 8-pin socket for the QFLD-840-2SM. The
> positive output pulse is applied to pin 2 of the diode. All other pins
> are grounded. Rseries in the output module is approximately 42 Ohms,
> such that Rseries + Rdiode = 50 Ohms, approximately.
>
> Other: as per the standard AVO-9A-B-P, described at

Optics

Adjustable attenuator (up to 50 dB):

• 840 nm: VOA850-FC
• 1060 nm: VOA1064-FC

Collimator (in holder AD1109F):

• 840 nm: get custom aligned version of F280FC-B
• 1060 nm: F220FC-1064

Neutral density filter for fixed attenuation (between two retaining rings SM05RR):

• how much attenuation needed here?

Lens (in holder S05TM09 - does this need retaining rings?):

• 840 nm: C280TME-B
• 1060 nm: C280TME-C

Mounting

3-inch lens tube: SM05M30

Lens tube clamps (two per tube for stability): SM05RC

Stage

Bottom of X stage is 3-3/8" high. Bottom edge of Z stage (Deltron LRS2-1) moves from 6-1/2" to 7-1/2" high.

About 1 m run from stage to the back of the hood; 1 m from back of hood to electronics.
