A20: The 5 mW laser output is the overall output power. When the laser is projected in a line or other shapes, the total power is spread over the entire output. Typically output power is measured via a 7mm aperture. Therefore only small portion of the overall output power is measured. Q21. Is the output power of the listed lasers adjustable? A21: Most laser system has this feature. For most laser modules this feature can be added as an additional feature for nominal cost. Q22. Do your lasers have capability to be interfaced to (controlled by) a computer? A22: Yes, most of DPSS laser systems provide computer interface for laser monitoring and control operations remotely via a PC compatible computer. Interface is electrically isolated and done via serial port (RS-232 or Com-port). A MS windows driven software is provided to perform all functions. Presently the following functions are available: 1. Read and display output power 2. Read system status information 3. Turn laser on/off 4. Set
