7.1 Laser installation in LLH housing
CAUTION:
Do not touch the bonds nor the laser chip itself, as the QCL may be
permanently damaged.
CAUTION:
Avoid any dust to deposit on the laser chip or any laser submount
item. Malfunctioning or permanent damage to the laser may occur.
7.1.2. Contact set
The contact set shown in figures 7.2 connects the laser active pad to the low impedance
line of the LLH through a copper contact, as shown in figure 7.3.
Figure 7.2.: LLH contact set, top (left) and bottom (right).
The laser submount is screwed onto the LLH base copper plate, on which the con-
tact set is screwed to insure electrical contact between the selected pad and the low
impedance line, as shown in figure 7.4. The low impedance line (LBI) connects the
laser chip to the LDD in pulsed mode, or external power supply in CW mode, through
the LLH laser and base connectors.
