Note
» The Laser is designed to operate without heat sink. Do not restrict air circulation around the device; an additional heat sink can be used to maximize the performance and life time of the laser. » All specifications are based on performance at full output power and after the specified warmup period. Output characteristics may change if the laser is run at a different power level. » 1KHz TTL modulation, 10KHz TTL modulation, 30KHz TTL modulation and 2KHz Analog Modulation are available upon request. » 2-Year Warranty is available upon request.
