◆SLM Laser |
|
CNI Laser manufactures compact
diode-pumped solid-state (DPSS) single
frequency/single longitudinal mode lasers with
narrow linewidth (<10-6 nm) and long coherent
length (>100 m). The laser operates in single
longitudinal mode and TEM00 mode with low
amplitude noise and high stability.
CNI can offer SLM laser in wavelengths (nm) of:
360
457
473
523.5
526.5
532
556
561
577
589
639

660
671
721
1047
1053
1064
1313
1319
1342
Another option of
narrow linewidth laser which includes
diode laser and
DPSS laser. The linewidth of diode
laser is <0.03nm, and <0.003nm for DPSS laser.

◆Frequency Stabilized
SLM
Laser |
In addition to
narrow linewidth and long coherent length, the
frequency stabilized SLM laser has the
advantages of stable frequency and low frequency
noise.
• Frequency shift (8 hours): ±200MHz
• Frequency shift with Temperature: <200MHz/℃
CNI can offer frequency
stabilized SLM laser in
wavelengths (nm) of:
360
457
473
532
556
561
639
656

◆Modulated SLM
Laser |
Modulated single
frequency laser has the advantages of quick
modulation rate, high extinction ratio, and easy
coding.
CNI can offer modulated SLM
laser in wavelengths (nm)
of:
473
532
556
561
671
• Repetition rate: Up to 1MHz
