The diode lasers of the Bluephoton® / Greenphoton® / Redphoton® DC180 DualChannel Series are temperature-stabilized laser diode modules with 2 modulation inputs in each case, for digital (On/Off) and analog modulation (power control). The two digital modulation inputs (up to ~200 MHz) are available either as 0…1 V / 50 Ohm or as LV-TTL (low voltage TTL) inputs. The analog modulation inputs have an input voltage of 0 … 1 V. The digital inputs are provided with programmable trigger levels, so that the switching point of the laser can be adapted to the input signals. The power to be switched per digital input can also be programmed. By means of the four binary possible combinations (00, 01.10 and 11) of the two digital inputs, the laser can be switched very fast between 4 different power levels. The extremely short rise and fall times of the digital modulation of <1 ns (nanoseconds) enable precise switching of the laser light in extremely fast processes, such as for example digital data storage, in CD and DVD mastering, as well as in microlithography. As a result of their intelligent laser controller with interface RS-232, these lasers can be integrated seamlessly into applications and controller. Through the standardized “Command Line Interface” (CLI), you have at all times full control of all parameters of the laser, such as e.g. laser diode temperature, laser powers and currents, operating modes and lots more.
The systems consist of a laser head and a laser controller in the EMC-screened modular housing and a low-noise power supply unit with an input voltage of 90-24 V, 50/60 Hz. As in case of all lasers of the Bluephoton® and Redphoton® Series, the laser head can be very simply adapted to customer specifications by the use of the modular principle.
