			The water levels in the chillers should be checked periodically (e.g. once a month). Using not enough water could impact the laser stability and could damage the chiller. The ThermoFischer chiller requires deionized water. If the canister in the lab is empty it can be refilled directly at the ITG in room 105 (from a canister next to the sink) or in room 143 (there's a Millipore Synergy Water Purification System).

	The optical tables rest on vibration isolation feet (Newport PL-2000; even at Newport there seems to be no manual for the PL-2000, their service recommends to use the I-2000 manual). The isolators are passive, that means they have no direct connection to a pressurized air line. Instead, they have to be re-pressurized manually every once in a while. There is a foot pump available for this purpose. The typical air pressure according to the manual is 10 - 85psi (0.7 - 6.0 kg/cm²).

			There are two chillers in the lab. One is located inside the rack (PolyScience Recirculator) and cools exclusively the Empower Pump Laser. The temperature setpoint is at 18°C.

			The second chiller (ThermoFischer Merlin M25) is outside the rack. The cooling water (deionized water) goes through the Millenia, Tsunami and finally the Spitfire, where it cools the High-Voltage unit and the removes heat from the Peltier-cooled crystal. Most heat is generated at the crystal when the Empower output is turned on. The chiller's setpoint is at 17°C, the pressure should be below 40psi.

Innolas Laser: changing the wavelength

	* Max Average Power: 800mW		* Max Average Power: 800mW
	* Jitter to external trigger: < +/- 0.4ns <!---->		* Jitter to external trigger: < +/- 0.4ns <!---->

			=== Changing the wavelength ===
			The output wavelength depends on the settings of two thermal controllers inside the laser head, TEC4 and TEC5. These temperatures can be set on the controller unit. The optimal values for 532nm or 355nm operation can be found in the manual. As of October 2016 these values are:
			* <span style="color:green">532nm</span>: TEC4 = 44.0°C TEC5 = 54.2°C
			* <span style="color:blue">355nm</span>: TEC4 = 55.3°C TEC5 = 54.0°C
			The controller "forgets" its settings after being disconnected from the power grid, you then need to set the values again after startup.

			You need also to change the output caps at the laser head. Unused output ports have a beam block on them. So when changing the wavelength you need to open the required port and put the blocking cap on the previously open one.
