ESLT – 045 is a hardware controller of the electrical system of a solid - state pulsed laser. The controller services, in a complex way, all laser subassemblies, and, of course, co-operates with a software controller. The hardware construction of the controller gives a very high level of safety of laser operation owing to its resistance top interference and stoppage of the system. It is known that these types of lasers are characterized by a high-level interference, which is often a cause of stoppage and improper operation in software controllers. The controller can co-operate with all types of lasers operating on a basis of a flashlamp. An additional advantage is the possibility to service two laser heads within one piece of equipment.

ESCON-040 Hardware controller for CW lasers Features: - linear control of the lamp power (control of voltage and current ratio) - control of current source converter - control of ignition circuit of the lamp - control of q-switch driver - control of average laser output power by closed loop between power meter and q-switch VCO - control of shutter - independent control of q-switch driver - servicing of alarm signals --"over temperature of cooling medium" --"over temperature of the head" --"over flow of internal cooling medium" --"over flow of external cooling medium" --"over load" --"over temperature of power supply" --"lamp failed" - servicing of "foot-switch" and "door-switch" signals
The ESCON - 040 hardware controller is designed for complex servicing of the solid - state lasers pumped with a CW arc lamp. Its construction is characterized by high resistance to interference, owing to applying a galvanic isolation of the system from the remaining laser systems.

ESUP-020 Microprocessor controller for solid - state lasers Features: - control of laser output power - control of energy of pulsed laser - control of PWM - frequency control for pulsed laser - control of shutter - control of two electrical valves - control of Q-switch driver - servicing of alarm signals --"over temperature of cooling medium" --"over temperature of the head 1" --"over temperature of the head 2" --"over flow of internal cooling medium" --"over flow of external cooling medium" --"over load" --"over voltage" --"over temperature of power supply" --"lamp 1st to 4th failed" - servicing of "foot-switch" and "door-switch" signals - servicing of alpha-numerical LCD display and LED numerical display - optically isolated inputs and outputs - galvanic isolated uP system - four analog reference outputs - four analog measure inputs
The microprocessor ESUP - 020 controller is intended for full servicing of solid - state lasers pumped by a CW flashlamp. Its construction features high resistance to interference owing to applying the isolation of the microprocessor system from the remaining laser subsystems. Individually a version of the software is prepared for a given controller. As an user’s interface, there are alphanumerical LCD numerical LED and keyboard attached to the controller. A compact metal case and standard connectors make the controller easy to use and assemble
Technical parameters: supply voltage +24 [V] inputs open collector outputs open collector output frequency 1-200 [Hz] outputs reference voltage 0-5 [V] measured voltage 0-5 [V]
