Webthat any laser beams must never come anywhere near your face or eyes; always enclose the output beam in a suitable beam dump. 2. Circuit description The circuit described here consists of two independent circuit blocks which share the same printed circuit board. The first is the laser current driver and output power monitor and the second is the Webforward voltage drop (if the load is a laser diode or LED). The driver cannot provide the required current if the compliance voltage is insufficient. For example, consider a 60 A current driver that has a compliance voltage of 20 V and typically drives a single-junction laser diode. You cannot test the driver at 60 A using a 1 Ω resistor for http://www.ichaus.de/wp4_fastlaserdriver how to remove pigtail chest tube
