The lasers of the CWA Series are highly-stable, temperature-stabilized diode lasers, with powers up to 500 mW and on request, modal jump-free CW operation. The high-precision temperature stabilization to a maximum diode temperature variation of <0.02°K and the stable power source for the laser diode, enable extreme power stability and very low noise levels. The systems consist of a laser head and a laser controller in the 19” cassette housing, with integrated 90-240 V AC 50/60 Hz power unit for global employment. The integrated modulation inputs for analog power modulation with up to 1kHz, and TTL modulation with up to 10k Hz, enable integration into control and measurement processes. 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 Specifications CWA-Models Blue- / Greenphoton® CWA Redphoton® CWA Wavelengths & Powers(other wavelengths and powers on request) Single-Mode (SM): Single-Mode (SM): 375nm / 20mW 635nm / 5mW 375nm / 70mW 637nm / 150mW 395nm / 120mW 639nm / 40mW 405nm / 55mW 643nm / 150mW 405nm / 120mW 647nm / 150mW 405nm / 300mW 658nm / 130mW 415nm / 120mW 670nm / 15mW 425nm / 120mW 685nm / 35mW 445nm / 50mW 785nm / 120mW 445nm / 100mW 808nm / 200mW 457nm / 100mW 830nm / 200mW 460nm / 100mW 852nm / 150mW 473nm / 20mW 980nm / 150mW 473nm / 80mW 1016nm / 100mW 473nm / 100mW 1060nm / 100mW 488nm / 20mW Multi-Mode (MM): 488nm / 60mW 638nm / 250mW 488nm / 80mW 670nm / 500mW 488nm / 100mW 808nm / 1000mW 488nm / 150mW u.v.m. 488nm / 200mW 515nm / 25mW 515nm / 50mW 515nm / 80mW Multi-Mode (MM): 375nm / 200mW (M² = 7…8) 405nm / 400mW (M² = 5…6) 405nm / 600mW (M² = 5…6) 445nm / 500mW (M² = 2…3) 445nm / 1200mW (M² = 5…6) Beam diameter 1.25mm (1/e²) /- 0.25mm 1.25mm (1/e²) /- 0.25mm (other diameters on request) (MM beam diameter may vary) (MM beam diameter may vary) Beam quality M² <1.2 (SM) <1.2 (SM) <3 (MM) <10 (MM) Astigmatism (corrected) <0.2*ZR <0.2*ZR Beam ellipticity <1.1:1 (SM) <1.1:1 (SM) Polarisation >100:1 vertical >100:1 vertical Power stability* <0.5% / h <0.5% / h Noise 0Hz-100MHz* <0.5% peak<>peak (CW) <0.5% peak<>peak (CW) Modulation speed Analog: 100Hz Analog: 100Hz Digital: 10kHz Digital: 10kHz Supply voltage 85-245VAC, 50/60Hz Features Safety-Interlock LCD-working-hours display Remote-connector Options LDM.COL – collimator objective LDM.FOC – customized focussing objective LDM.FASY.XXX – fibre coupling unit * Noise and power stability values of IR lasers and multi-mode lasers may vary
